We don't have a long of natural resources as a country; we have a very beautiful country. Visually, I mean, everyone goes on about it's green, it's the mountains and the rivers and it's clean and it's not that populated. It is stunningly beautiful, but we've no oil. We've no coal. We've no money. We just have Ireland.

My main influences - I loved art. I sounds a little pretentious to say I was into art but I liked drawing. I liked music; music was my outlet from day one. I was giving you an image of Ireland being this dull, grey, massive unemployment, not much going on and the future was the dull queue or - and, for me, the window of hope was music and books. So I fell in love with sort of T-Rex and David Bowie very young. They sort of said, "Hey. You don't have to live in this north side of Dublin that's all grey and depressed. You can be a spider and go to Mars."

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.

I've always as a performer on stage tend to sort of throw myself into the character, whatever I've written about, so it depends on how I'm writing or what I'm writing about.

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.

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.
