A weird theory I have is we come from a suppressed culture. Ireland is one of the most invaded countries ever. I think the British started it very early, it could be like 800 that decided to come and show us out; and the Danes in the north. We've had a tough time and pretty much a similar culture would be the Jewish culture; they had a pretty hard time. They were being kicked around for a long, long time.

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.

You've got to use alcohol and not let it use you. I come from a country that's been doomed by alcohol. The Irish could drink; they could drink Europe. And they'd have a good go at America, too. I mean, you guys - your alcohol is like not good, it's weak.

There is a terrible thing that's been happening probably for the last 20 years or so and it's called the music business. And music isn't really business; it's work and you got to pay and you've got to buy your guitar or go into the studio. So there is a business side but when people say, "I'm going into the music business," it's not. It's about expression. It's about creativity. You don't join music, in my mind, to make money. You join it because it's in you; it's in your blood stream.

We had similar interests with Derek Rowan and Paul Hewson; it sounds really pretentious at 12, 13 year old kids were like into art and poetry, but we were. We weren't into football, we were into making music or being into music and painting and stuff like that. And we called this sort of little gang Lypton Village and we made up imaginary games and this is one day we'll form bands and one day we'll make movies and one day we'll do this and one day we'll do that. A lot of kids do this in their own way, except 25, 30 years later legend happens because some of us have become quite well known.

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.

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.
