I'm interested in feedback and learning what people want. It's a tricky thing for me when I do a set list. You get bored doing the same songs. Let's say we do one ballad in two hours, and it's "Wild Horses." If you say, I'm tired of that, let's try something less well known, and then you're out there stumbling through this song you just relearned at sound check, and you realize people probably want "Wild Horses" instead of this. You do need to do some songs that aren't so well known. The question is how many? I'm open to people posting their requests.

It's a real buzz, even in front of 20 people, to make a complete fool of yourself. But people seemed to like it. And the thing is, if people started throwing tomatoes at me, I wouldn't have gone on with it.

I suppose you do think about the time that's allotted to you more than when you were younger. The mortality thing obviously has a stronger pull for you. It's an imminent truth; it's not necessarily a bad thing. You realize - much earlier than my age now - that you won't be able to play for England's football team, just to take a really crass example. So you can't have that life again. Unless you believe in reincarnation or whatever. Reincarnation? That's a whole other question. I find people who talk about that sort of thing in interviews idiotic. And I don't want to go down with them.

The Spice Girl Victoria Beckham has just published the story of her life. I confess that it is not in my reading table.

You've got to have fresh wardrobe. You can't just go out there looking like you did last time. That helps your transformation.

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.

I see songwriting as having to do with experience, and the more you've experienced, the better it is. But it has to be tempered, and you just must let your imagination run.
