And if I had to spend 20 years in the band just to play that show, I think it would have been worthwhile.

It's a tough life being a pop star. You know, at the end of the day when you've paid all the bills and put the kids through college and that, you know, there's only enough left for a small island off the South Pacific.

When you're in the music business, everything is very personal, because you are invested in everything; there's a very deep, personal attachment to your music.

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.

People say, 'Why don't you do interviews? What do you think about this? What do you think about that?' My job in the band is to play drums, to get up on stage and hold the band together. That's what I do. At the end of the day that's all that's important. Everything else is irrelevant.

Then Bono arrived, and he meant to play the guitar, but he couldn't play very well, so he started to sing. He couldn't do that either. But he was such a charismatic character that he was in the band anyway, as soon as he arrived. I was in charge for the first five minutes, but as soon as Bono got there, I was out of a job.

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.
