I joined a band to hit things.

There's a thin line between interesting music and self-indulgence. We crossed it on the Passengers record.

Unfortunately, as far as the music is concerned, what defines relevance is whether you are on the radio or whether you are on the cover of a magazine or whether you're winning MTV awards, and so on and so forth.

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.

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

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.

I will never be a career actor, I don't think. I don't feel that I have the skill set to jump into it that way, although I wouldn't mind giving it a try.
