Einstein got most of the things right about black holes. I'm not an expert, I must admit

We do play to our audience. It's very important. You can't create music in a vacuum.

There are times when I flick through magazines and think I'm in danger of becoming a prisoner of my own hair.

I think music is about our internal life. It’s part of the way people touch each other. That’s very precious to me. And astronomy is, in a sense, the very opposite thing. Instead of looking inwards, you are looking out, to things beyond our grasp.

I like a big neck – thick, flat and wide. I lacquered the fingerboard with Rustin's Plastic Coating. The tremolo is interesting in that the arm's made from an old bicycle saddle bag carrier, the knob at the end's off a knitting needle and the springs are valve springs from an old motorbike.

Every time I listen to Jeff Beck my whole view of guitar changes radically. He's way, way out, doing things you never expect.
