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!

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

The only term I won't accept is "genius."

You don't find geniuses in street musicians, but that doesn't mean to say you can't be really good.

The gut-strung guitar, the classical guitar, that is a whole different world on its own. When you think what the guitar can do and what every individual player does with a guitar, everyone has their own identity coming through the guitar.

I really wasn't needed... Just straightening up riffs, that's all. Just two guitarists doing it instead of one.

There's such a wealth of arts and styles within the guitar... flamenco, jazz, rock, blues... you name it, it's there. In the early days my dream was to fuse all those styles. Now composing has become just as important.
