Success is buried in the garden of failure.

When the first list was being drawn up in the rock and roll book of Genesis, it would have been: In the beginning, God created Pink Floyd.

But I'd play on everything from pop records to a lot of the glam stuff to rock stuff to classical stuff. I used to get called to do all those things, it was great.

Success is buried in the garden of failure.

Coming back to Yes is like never having left. Even when I have not been in the band, I have always felt part of it.

I read numerous books - loads in fact - and, as I always do when recording a historical project, immersed myself into the subject matter. I spent many hours at Henrys old homes, such as Hampton Court, and visiting the Tower of London. I read no other books during that period.

Even the two times that I left, I never really felt like I left the band. It's very bizarre. It's like there's sort of an umbilical cord that stretches between us spiritually.
