Biographies of British pop celebrities are terrible.

You know, being in a rock band, you can't overdo the costume changes too much because everyone thinks, oh, that's not a real rock band. Look how many times he changes costumes. That's not rock. Rock's about going on in a T-shirt and staying in it and getting it all dirty. But that's not really my approach.

One song isn't going to ever change things, but I suppose it's the accumulation of music generally [that is]. If you can imagine a world that has no music in it, it would be a very different world, so music does change the world by virtue of all the music in it. Cumulative music of every kind, from banging a drum to playing a flute or recording symphonies, or singing 'War, what is it good for?' All those things change the whole way we live.

Americans are funny people: first you shock them, then they put you in a museum.

I must be careful not to get trapped in the past. That's why I tend to forget my songs.

I think that people taking drugs occasionally are great. I think there's nothing wrong with it. But if you do it the whole time, you don't produce as good things as you could.

I, personally, have a lot of energy, so I don't see it as an immediate problem.
