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.

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.

I was a very shy child. I didn't like football. I didn't like the usual stuff that was shoved at. Sports were always down you and the Gaelic language, which I've actually disliked as a kid but as I grow up I quite like it.

The last 15 years we had one of the biggest economic booms. But I think a few bubbles have burst in a few countries. So we are all going through the same things. But let's say Ireland, in the '70s and the '80s was tough, but if you grow up with a tough background it makes you strong.

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.

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.

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.
