I wanted all the music to sound strong. It's all down to the restoration and mastering. In many ways I feel the work in general was never properly mastered in the first place. To me, making the music sound the way we wanted it was by far my biggest goal with the re-issues.

The Catholic church had a huge profound influence on me in that as you get older you realize that you can't blame everything; that there is good and bad, and things get misdirected. So I would call myself a black Catholic. I still have this attraction to it because all religions I'm not a fan of. I'm a fan of sort of belief in spirituality. So I would be into Christ rather than the Catholics.

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.

Our language was even taken from us. The Irish Gaelic language was outlawed and the religion was outlawed. Hence the religion later being stronger; stronger to a negative point of view. But our venge was, I mean if you listen to Irish language, it's very complicated but it's very poetic.

I like a fine wine. Who can beat that? I don't think it helps writing; I think it's a hinderance. It helps numb you.

I think a lot of kids do dream in their own way, except 25, 30 years later legend happens because some of us have become quite well known. So the myth becomes magical. So I tend to sort of see it very practical for me. When I go out for a drink, Bono can buy the pints because he has more money than me. We're the same guys, do you know what I mean.

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.
