Yes bassist Chris Squire is writing his autobiography.
The 66-year-old musician, who rose to fame in the progressive rock band in the late 1960s, has been working on his memoirs with actor friend Vincent Gallo and hopes to sign a publishing deal within the next year.
He exclusively BANG Showbiz: "I sit down with him, we talk, we record it, then he goes and transcribes it.
"We're about half way through that and have been working on it for about a year.
"We have to schedule time, he lives in Los Angeles and I live in Phoenix in Arizona. We have to find time to do it, sometimes I'll go to him, sometimes he comes to me."
Having previously spoken about his experiences with LSD and marijuana during the 1960s, the book is expected to detail crazy nights on the road as well as chapters about his earlier life and his love of music.
Chris explained: "It's a general overall conversation about my life. Hopefully within a year we'll be able to wrap it up and get it out there. We haven't signed a deal yet, we'll get it written first, I've talked to various people about doing it before.
"I'm sure there will be juicy stuff in there but [groupies] is not going to be the main aspect."
He joked: "Let me see ... there were probably three or four thousand [though]."
The band - which has had a number of line-ups over the years and features new frontman Jon Davison - were also in talks about a Broadway musical but Chris insists there are no plans for it to go ahead at the moment.
He said: "It was a good concept but it's like any Broadway show, it's on six or seven nights a week, you have to put bums on seats for that amount of time. You never know with these things, it could work, it might not work."
Yes will release their new studio album 'Heaven and Earth' on July 8.

The Kinks' Dave Davies claims his relationship with band mate and brother Ray is "toxic."
The siblings haven't played together since 1996 after a number of arguments and the 67-year-old guitarist claims he doesn't want to spend too much time with him anymore.
Speaking to The Independent newspaper, Dave said: "The thing is, there's healthy relationships, and toxic ones. And the older I get, the more difficult I find it being around Ray, because - I don't want to use the word abuse - but I feel my energy seeping away from me sometimes if I'm with him."
Dave insists he doesn't want to be "stuck" in a place feeling jealousy, hatred and envy and "generally being unhappy" around the band's frontman.
He explained: "Being with Ray for too long gets me back in that cycle. But then, families are difficult, and you can learn from discomfort. Ray and I have been each other's most important teachers. Maybe that's the clue to the whole relationship."
However, he also claimed that there was no animosity between the pair, saying: "It's like some people prefer me and Ray to be at each other's throats than to be brothers.
"In my 30s and 40s, I resented the fact that Ray gave me so little credit for my input and creativity. But my love has always been relentlessly directed towards him."
Dave will play his first UK show in 13 years on April 11, with a gig at London's Barbican Hall, and in January Ray discussed a possible reunion for the band's 50th anniversary, which he claims was "as close as it's ever been to happening".

Iggy Azalea has defended her Biggie Smalls remake.
The 23-year-old hitmaker worked with singer Keyshia Cole and sampled the late rapper's 1997 posthumous release 'Mo Money Mo Problems' and Iggy insists it wasn't meant to be a rip-off.
She told America's RapFix Live: "First of all, I love Biggie forever and Tupac, and that's a sampled song. So don't be mad about something that's sampled already."
The 'Fancy' hitmaker went on to explain how music producer Irv Gotti initially approached her about modernising Diana Ross' 1980 hit song 'I'm Coming Out'.
She said: "Irv hit me up and said, 'Hey I've got a record with Keyshia on it and it's gonna be for the soundtrack to this Cameron Diaz movie 'The Other Woman'.
"It was just supposed to be a remake of 'I'm Coming Out', it wasn't supposed to be 'Mo Money Mo Problems', and I didn't know what I was getting into."
But despite critics reacting badly to the release, she insists she's proud of the record and wouldn't go back on her decision.
She said: "I'm from a generation where I don't think 'I'm Coming Out' - I think 'Mo Money Mo Problems'.
"So I thought, I need to get my Ma$e on, and I went with that vibe. Then I think when people heard it they said, 'She's doing the Biggie remake,' and I don't know if it was necessarily meant to be that. It's open to interpretation. I didn't know what I was getting myself into, but if I did I would've said yes. Because any rapper that gets asked to do that is gonna do that."

Russell Brand is hosting a documentary about drug addiction for BBC Three.
The comedian-turned-political activist - who is a recovering alcoholic, heroin user and sex addict - has signed up to front a one-off programme called 'Russell Brand: Give It Up', which will see him interview addiction sufferers and people in positions of power as he investigates addiction treatments around the world.
The 60-minute Matchlight show will be a follow-up to his 2012 documentary 'From Addiction To Recovery', according to Televisual.com.
Russell's aim is to investigate how to improve treatment for addicts in the UK, and will see him travel to Switzerland where his views on abstinence-based recovery are challenged.
As well as speaking to key political decision-makers, government officials and police staff, he will chat with addicts from all walks of life who are currently battling or have overcome their dependency issues.
'Russell Brand: Give It Up' is just one of many new factual and current affairs shows commissioned by BBC Three controller Zai Bennett.
He commented: "BBC Three is the only channel that commissions original documentaries and current affairs specifically for young adults. These shows cover a range of topics from the war in Afghanistan to life at Bangkok airport, from a pupil referral unit in West London to drug cartels in Mexico.
"They demonstrate the range and quality that BBC Three viewers expect from our top-fight factual content like recent agenda-setting documentary 'Life And Death Row'."

James 'Arg' Argent thinks his relationship with Lydia Bright is irreparable.
'The Only Way Is Essex' star split with his girlfriend of four years following revelations he'd cheated on her and as he prepares to release his tell-all book 'Living It Arg' he's confessed that he doesn't see any way back for them.
He said: "When we did break up, initially it wasn't a nice break up. It was bitter and angry and at the moment it seems irreparable, but who knows in the future."
The 26-year-old reality TV veteran - who's been absent from only one episode out of eleven series of TOWIE - blamed his change in lifestyle when he joined the show for his infidelity.
He explained to 'This Morning' hosts Phillip Schofield and Holly Willoughby: "When TOWIE first started I didn't have any money, no attention from girls and as soon as the show started ... Lydia was the only girl I'd ever been with and I didn't deal with the fame too well.
"We haven't had any proper contact for about a year and a half, but I'd like to think that the book explains everything to Lydia. I think she'll have comfort from knowing the reasons why I did it and the fact of how genuinely sorry I am."
Lydia made her first appearance on TOWIE since her departure in 2012 on last night's (02.04.14) season finale.

Sam Faiers is "disappointed" with her final episode of 'The Only Way Is Essex'.
The blonde beauty starred in the ITV 2 reality show for the final time last night (02.04.14), but was left disappointed when she realised a significant portion of the emotional farewell she'd bid to her co-stars had been edited out.
Sam wrote on Twitter: "Can't believe my last ever scene was cut down...I said some lovely things to & about everyone over the last 4 years...Very disappointed. (sic)"
During a heartfelt chat with co-stars Jessica Wright and James 'Arg' Argent, Sam revealed she wanted to "step off the Essex scene for a little while" to focus on her health following her diagnosis with Crohn's disease earlier this year.
The 22-year-old beauty also admitted that she had rekindled her romance with ex-fiancé Joey Essex and confessed she wanted to concentrate on their relationship.
Joey, 23 - who left the show last year - congratulated Sam on her decision to leave, writing: "I'm so proud of her. Well done my baby (sic)."
Former co-star Mark Wright also took to Twitter to praise her "amazing efforts" on the show.

Samuel L. Jackson has revealed workers in Cleveland thought he was being shot at when he filmed scenes for 'Captain America: The Winter Soldier'.
The actor reprises his role as super-spy Nick Fury in the Marvel sequel - which sees Chris Evans return as the titular superhero - and he recalls one shoot-out sequence filmed in the city left some office staffers fearing for his safety.
During an interview on 'The Daily Show' - which airs on 'Comedy Central' and 'Comedy Central Extra' - Jackson said: "At one point in the movie there's a moment where you see 19 guys shooting at the car I'm in, the windows are bullet proof so I'm just sitting there feeling dope but the people in the office buildings didn't know so they were looking out of the windows and were like, 'F**k!' "
Jackson is now a veteran of superhero and sci-fi films having appeared as Nick Fury six times with a contract to appear in another three movies and the three 'Star Wars' prequels.
The 65-year-old actor portrayed Jedi Knight Mace Windu in the trilogy and was thrilled when director George Lucas told him he'd make him look like the "baddest" man in the universe when he added CGI to his green screen scenes.
Jackson explained: "Lucas said, 'You kick all the ass you want and we will make sure you look like the baddest motherf***er in the universe!
"So (I'm shooting and) I have the music playing in my head, making the lightsaber moves and then when I go to see it in the theatre I was like "F**k! Look at me!' "

Quentin Tarantino's court date against Gawker has been set.
The director will face off against the website, who he is accusing of contribution to copyright infringement, in court on January 27, 2015, a year to the date of the filmmaker filing the $1 million lawsuit, Deadline.com is reporting.
Tarantino was furious when Gawker posted a link to a leaked copy of his 'Hateful Eight' script, forcing him to scrap plans for the Western, but the site maintains there is no case and says directing people to an online version of the script was fair use as it hadn't "reproduced" the material.
The three-day trial may allegedly not even take place since Judge John F. Walter has moved the matter to private mediation.
The hearing for April 14 has now been dropped, and the two parties will have until September 8, 2014, to complete the mediation and prepare their cases.
This comes two days after Gawker hit back at 'Kill Bill' helmer Tarantino for the second time, stating that his claim "misconstrues, misunderstands, and misstates" the law and accusing him of only pursuing the matter because of his "displeasure with Gawker's past and present reporting about him."
The award-winning director claims he only gave the script for 'The Hateful Eight' to six people and believes one of them must have let their agent see it, who subsequently sent it on.

Kendra Wilkinson's second pregnancy has been "brutal".
The former Playboy model - who already has four-year-old son Hank Jr. with husband Hank Baskett - is due to give birth to a baby girl in the coming weeks and she admits it is becoming a struggle to move around.
She said: "It's easier on the mind, harder on the body. It's been brutal. I think because little Hank stretched me out, I know that sounds pretty gross, but he stretched me out all the way! I think she got a chance to sit lower faster, so she's been on my pelvic bone all pregnancy.
"Like, I'm seriously done! It's over, like my life is over right now. I'm trying so hard not to be bedridden."
The 28-year-old beauty is particularly worried about her waters breaking and going into labour when she is out at an event.
She told E! News: "The weirdest thing is standing about to go on a red carpet and praying that this pee I'm peeing isn't my water breaking!
"I literally cross my legs hoping my water isn't breaking! It's pee, it's fine."
Kendra and Hank are doing their best to involve their son in the pregnancy.
She said: "Little Hank is super excited. We're trying to get him to feel like he has a role. I'm the mom, Hank's the dad and he's the protector. I want him to feel empowered through this and feel loved still."
And the couple have a shortlist of names for the new arrival, but won't choose one until they meet her.
Kendra said: "We have a good five [names] We have a top five. We're going to have to see her and name her."

Rob Kardashian is getting advice from Lamar Odom.
The reality star has distanced himself from his family in recent months and was noticeably absent from their holiday to Phuket, Thailand, but has reportedly decided to reach out to his former confidante, his sister Khloé Kardashian's estranged husband Lamar, in his time of need instead.
An insider told RadarOnline.com: "He has completely retreated from the family, and from his friends. But within the last few weeks, Rob has reconnected with Lamar.
"It was extremely hard for Rob when Lamar and Khloe split because first and foremost, he hated what it did to Khloé. The split also essentially had ended Rob and Lamar's relationship... they called each other brother, and meant it. There was a lot of love there."
Lamar is said to have asked Khloé's permission to rekindle his friendship with her brother and she refused to stand in their way.
The source added: "Lamar asked her if it was OK if he reached out to Rob, and of course, she said yes. No matter what happens with them in the future as a couple, Khloé wants her brother and Lamar to maintain their friendship."
The NBA star is determined to get his pal back on track as he is said to have been suffering from depression following his ugly split from Rita Ora in 2012 and has gained 50 pounds.
However, it seems camera-shy Rob has no interest in flying out to see Lamar in New York City.
The insider said: "Rob just isn't receptive to that. It has come to the point that he just hates going out because of the constant cameras always around. Lamar is planning to come to LA in the next month, and they will definitely hang out then."

Alex Turner can't help but write songs about women.
The Arctic Monkeys frontman, who previously dated model-and-presenter Alexa Chung, admits most of his band's tracks are about the ladies in his life but claims they are also inspired by loneliness.
Speaking in the May edition of Esquire magazine, he said: "I write about women, yes. I haven't really found a way round it yet.
"There's other things I eventually might get round to writing about. But for now ... in a sense they're about girls. But in a sense they're about loneliness. And longing."
Despite being known for his outspoken opinions on rock 'n' roll, he often hides behind his music and doesn't like being in the spotlight.
He explained: "I'm in a difficult position in the sense that, preposterous as this might sound, I don't like being the centre of attention.
"I don't even like opening my birthday presents in front of people, either."
However, the 28-year-old singer insists he can laugh at himself and feels it's what helps him cope with being in the music industry.
He said: "Certainly, in this day and age, a sense of humour [is important].
"Because it's pretty ridiculous. Not to name-drop but we bumped into [Led Zeppelin frontman] Robert Plant last night and he's hilarious. Just funny, straight away. These days I think if you start taking it too seriously, which I'm, like, sometimes definitely in danger of doing ... then it gets ugly."

Nicki Minaj struggled to remember the name of her 'The Other Woman' co-star Leslie Mann.
The 'Starships' hitmaker makes a cameo appearance in the film and, rather than remembering the actress' moniker, she opted to just call her 'lady' instead.
Leslie said: "Nicki Minaj never remembered my name. She just referred to me as 'lady'.
"She would just say, 'Come, lady'. And I was like, 'OK!' "
However, Leslie's co-star Kate Upton thought the singer's behaviour was due to her being "overwhelmed and intimidated by the actress and fellow 'The Other Woman' star Cameron Diaz.
Speaking as part of a Twitter takeover for Yahoo! Celebrity, Kate told Leslie and Cameron: "You know why she probably didn't remember your name? It's because she was really overwhelmed.
"You remember I had that big mark on my back and you had both your heads in my dress. Because I hurt myself and you were checking me out and she was like, 'I have a feeling they're going to do that to me next!' "
In the movie, Nicki plays Lydia, the assistant to Cameron's character Carly, who is left stunned when she learns her boyfriend is married to Leslie's character Kate, and also cheating on her with a third woman, Amber, played by Kate.
