I had joined Yes in 1971. I was a classically trained musician who had worked with numerous artists as a session musician. I played on David Bowie's 'Life On Mars,' Cat Stevens's 'Morning Has Broken' and even on some Des O'Connor records, though I kept that quiet.
To play music, you have to understand it. I didn't understand 'Topographic Oceans.' That's why I hardly played on it. It frustrated me no end - and playing the whole thing on tour, I got farther and farther away from it.
