I can't even begin to describe how I miss him. He always supported me in everything I did. He was a very wise man and I realised at an early age I could learn a lot from him. He always gave me the right answer. But above all he was a very easy-going guy and all he wanted was to be my best friend. I'm an only child and so he shared everything with me. Of course he was very young to die and I was very young to lose a father. But there was nothing left unsaid between us.

I've grown up around cinema. Michael Kamen was a very, very close friend of mine, sort of my godfather. So I know how much work goes into it. You have to know what you're doing.

I never really saw my dad around when the Iron Maiden and the AC/DC were playing. But he knew what I was doing. I was just absorbing music. So he just kind of left me to my own devices.

It's funny, because music is one of those things it is natural to go into. You hear it so much growing up, it kind of permeates you and eventually you spew out some music of your own.

If you were the first person ever to design an application for the iPhone and you patented it, you would be very, very better off than we are right now, you know? But you've got to be the first one to do it. So I figured that Led Zeppelin or the Stones were going to do it unless we just got on to it. So I got cracking with the guys from Apple.

I did Albert Hall, I got to play the Hall of Fame with Prince. So I've done that kind of stuff for ages. It wasn't until after we finished working on Brainwash, my dad's album after he died, then it was like 'That phase is over in my life now, now we can get on with our music, with our band.'

I was an only child. I hung out with my parents.
