I was into David Bowie. I attracted long hair and earrings when it was quite a risque thing to do in Dublin. We didn't have the liberation that America and Britain in the '60s but I did always look to England and America, mainly because of the music that came from there.

I love the way an Irish man, they can hardly speak proper English, is doing William Shakespeare. So I find that extraordinary as I get older. But I always see music, live shows, performances as moments and to really get there you've just got to actually get into the essence, flesh and the blood.

I was a very shy child. I didn't like football. I didn't like the usual stuff that was shoved at. Sports were always down you and the Gaelic language, which I've actually disliked as a kid but as I grow up I quite like it.

I don't think Bono decided to be ambitious, he just is. But if this country ever ran out of electricity, just shove a plug up his hole and it would run for a week.

We became friends in Dublin through music and we had real names, Fionan Hanvey and Derek Rowan - what a dreadful name. And Paul Hewson. We gave each other nicknames just the way most kids do, but the nicknames had more to do with how we physically looked or our essence and I had quite square features as a young kid. I was called Wavin for awhile, but I'm a bit softer - I'm a little softer than a surge pipe so they changed that to Gavin. I didn't chose it, it was Bono and Guggi who gave it to me.

A lot of singers don't really know who they are. They have this massive insecurity and this massive ego and they are sort of pulled between both. I mean, why do you want a lot of people to look at you all the time and listen to you? There is something going on there, there is sort of need to express and attention. It's not just ego, it's some sort of complex thing and sometimes you create characters to say something you want to say and then you just throw yourself into that.

I have shot myself in the foot so many times, I'm crippled. Look, I am not exactly Mr. Great Career Guy. I shoot actually what I think. In a weird way, I used to think that was really messed up. Now I think it's okay. Mistakes, once you don't repeat the same mistakes, have no regrets. Live and learn. We mess up, so what. But know why you messed up and don't make the same mistake.
