Well, I think that it is complicated in that the first four albums were all with Universal so they have the rights to that and therefore it is a lot easier for them to do that period.

Now with Pro Tools, you can play with layers and 100s and 100s of tracks. When we used to do it back in the day, you had one shot, or you would have to wipe it and carry on over that track.

I think that Yes' music is kind of on its own out there, and it goes through different chapters, and that involves different people. I don't think it's a case of 'any year is better than any other.' They can all co-exist quite comfortably.

To some degree. I think that I've always been very much of a chordal person. The chords are the foundation of everything. Some of Yes' stuff is very linear, albeit complex, but it's single-line melodic stuff. So I kind of had to wear a different cap working with Yes. It's not so much chord-based.
