I don't even think any stimulants really help writing. You talk to most guys and they say, "Hey. I wrote this." And they're out of their head or they had a few beers or a bottle of whiskey. You wake up the next morning, it's usually pretty crap. But you know Dylan Thomas wrote some great poetry. Brendan Behan. You never know but ultimately I'd say you have to get up early in the morning and you're usually sober when you write your good stuff; it's hard work. So alcohol, keep it for chilling out, fun, and having a good time. Not for work.

Do you think I'm going to live until 100? I'll have to, maybe Bono can arrange that. That would be interesting. Hey Bono, thank you for my 50th, can you make me live another 50 years? It's just such a pleasure to be and an honor.

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.

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.

My heroes are all dead. I've lots of heroes. My mum is a hero. She had to put up with me and my dad. She is one of my heroes. Some of my friends are heroes. There are so many. But heroes usually let you down, don't they? There is people I admire, people I respect.

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.
