Relevance is a big, big question. It's more about what's your definition of being relevant. In the music world, agism is a big issue. It's about youth and youth culture. There's no other art form that I know that requires you to be a certain age.

Relevance, for me, is about being creative and doing things that you believe in, whether that's music or acting or painting a picture, or whatever that is.

The only thing I wouldn't like to do is to play roles as a musician. I'm not sure that I would be comfortable doing that, and I'm not sure I'd be very good at it. I think I would be better served, and would be a better partner, if I was in something outside of myself.

We all have views on what our Irishness means to us. Two members of the band were born in England and were raised in the Protestant faith. Bono's mother was Protestant and his father was Catholic. I was brought up Catholic. U2 are a living example of the kind of unity of faith and tradition that is possible in Northern Ireland.

It doesn't matter what songs we sing. I'm a drummer. Chicks dig me.

If Bono left, we could carry on. If I left, we'd be screwed.
