Whether you're writing a book or a song or whatever, you've got to be involved in it. It's got to come from the heart I think...that's what it's all about.

There was a conflict - the actual putting together of the reality of the situation didn't seem to gel. I'd been doing kind of a slow ballad type of thing on records, but when it came to performing, I felt I was limiting myself.

When I first started drinking, everybody was doing it. That was before they discovered marijuana and all that. It was the late 50s, early 60s - it was the beginnings of the rock 'n' roll era. The main drink was like wine. And even that was a romantic throwback to something.

I realized I was growing up or something like that. You have responsibilities...you've got to think about getting your act together. I didn't even know what it had been doing to me. I didn't realize how dangerous it was. People talked in terms of drugs and I used to think in terms of...well in Ireland, everybody drinks. Nobody gives it a second thought. You're Irish number one and you're a drinker number two. That's the first two things about us Irish.

Leave your thoughtlessness behind you then you may begin to understand. Clear the emptiness around you with the waving of your hand.

[Rock 'n' roll] music started out with some cat banging a log with a couple of pieces of stick. He sent a message across a river and although the cat on the other side receiving the message didn't know the exact words, he did understand basically something about what was being communicated.

Jazz goes into folk music, into rock music. Jazz is in practically everything except classical music where they're reading the same music all the time, the same way, the same tempo every night.
