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 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.

My real name isn't Gavin. I was given Gavin Friday by my friends. I'm christened Fionan Hanvey, which is Gaelic and there is no actual English translation. I hated it as a kid but as I grew up I sort of went, "Now I like it."

Socialism and Communism don't work, but neither does straightforward capitalism. We've got to get a new way of thinking and working. We blew it so there was good and bad about the celtic tiger. But we're tiny. There's four million in the country, do you know what I mean? We're tiny. Four million in a country, how many is in New York? Seven? Ten? But we're strong, so hopefully we pull through.

There was engrained poetry and then when you look back at our history and in the 20th century, the last century, probably the greatest writers of the 20th century were Irish. It became our only weapon, was our poetry, our music.

Music and books were my inspiration too. I read avidly as a kid. And that's the beautiful thing about books and music and even movies, is that you can actually escape. You can go into other worlds.
