I'm still searching for an angel with a broken wing. It's not very easy to find them these days.

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.

You get as much out of rock & roll artistically as you put into it. There's nobody who can teach you. You're on your own and that's what I find so fascinating about it.

I'm attracted by the unknown, but I take precautions.

I spend a lot of time near water.

There is far more sensitivity in acoustic guitar players than could ever be compared to any synthesizer. That's a personal point of view but that's the way I see it. I think that's what it's all about. The drive, the fire, the passion - it all comes out on the guitar.

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.
