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.
