Well, Led Zeppelin IV! That's it really. I'll tell you why the album had no title - because we were so fed up with the reactions to the third album, that people couldn't understand why that record wasn't a direct continuation of the second album. And then people said we were a hype and all, which was the furthest thing from what we were. So we just said, `let's put out an album with no title at all!' That way, either people like it or they don't... but we still got bad reviews!

I played guitar all my life, all the way through the Yardbirds, but I knew that for me this was going to be a guitar vehicle, because that's what I wanted it to be.

I deal in emotions. It's the harmonic side that's important. That's the side I expected to be much further along on than I am now. That just means to say that I've got to keep at it.

I don't like being stuck in one situation, day to day.

I like change and I like contrast.

I can tell how far I ought to be going, I know how to get there, all I've got to do is keep playing.

Live Aid did feel like one hour's rehearsal after several years, but to be part of Live Aid was wonderful. It reall was.
