My son is in a band, and he’s a singer, and his vocals … they’re screaming-growling stuff … and he’s got a pretty reasonable voice. Yet he practices really hard to get the screaming-growling thing without losing that voice every five minutes. So I’m, like, “Hats off to you.”

I guess it was the first time I really thought about leaving. I don't just mean Iron Maiden, I mean quitting music altogether. I just thought, 'Nothing is worth feeling like this for.' I began to feel like I was a piece of machinery, like I was part of the lighting rig.

Some of Eminem's rap songs kind of have the teenage love songs like the fifties love songs. It's kind of like domestic drama set to music. He is really good storyteller.

I guess that the salary that they get when they are working with me is, like, it beats working at McDonalds, so it has got some things going for it.

I enjoy making solo albums because over the years it's evolved into more of a genuine personal expression of story-telling and day dreams, and I work in a way that has more control.

I think the best way to find out about something is to try to do it to the max. A lot of people take up a hobby or sport and then find an excuse not to carry on with it. Once I start something, I won't stop until I'm as good at it as I'll ever be.

In the days when Glastonbury was an alternative festival, it was quite interesting. Now it is the most bourgeois thing on the planet ... we'll leave the middle classes to do Glastonbury and the rest of the great unwashed will decamp to Knebworth and drink a lot of beer and have fun.
