Things to keep in mind:
The secret of covers.
And one of the things a lot of people miss about Yes, I think, is that it was just a covers band. And we started out just doing covers of lots of songs of the day, big Beatles songs, typically, Crosby and Stills, and I don’t know, Fifth Dimension, and even some West Side Story probably. And we learned to play those; we didn’t have a shared repertoire. A lot of the bands—like, say, Black Sabbath or something like that—came from the same street in Birmingham, or from Detroit, or somewhere. And we weren’t like that at all; we came from all different cultures and parts of the UK, so we didn’t share a common music culture, a kind of rhythm & blues-based thing. We needed to take something and then change it, and it was through changing things that we came to know ourselves.
