I don't think anybody could imagine the life that I've been lucky enough to have. It's been an incredible journey.

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

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.

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.

I love the Elvis movies. I used to watch them. In every single one of his movies he wasn't acting as a car salesman - he was acting as a car salesman who loved to play guitar.

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.
