I'm obsessed - not just interested, obsessed - with folk music, street music, the parallels between a country's street music and its so-called classical and intellectual music, the way certain scales have travelled right across the globe. All this ethnological and musical interaction fascinates me. Have you heard any trance music? That's the thing.

I'm not afraid of death. That is the greatest mystery of all. That'll be it, that one. But it is all a race against time.

You can't buy time. Everything, for me, seems to be a race against time. Especially musically.

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

When you hear the melodic structures of what classical musicians put together and you compare it to that of a rock & roll record, there's a hell of a long way rock & roll has to go.

So far I've been very, very fortunate because it appears that people like to hear the music I like to play. What more fortunate position can a musician be in?

Right from the first time we went to America in 1968, Led Zeppelin was a word-of-mouth thing. You can't really compare it to how it is today.
