I did everything I could to not be a musician.

The music I want to hear in my head sounds somewhere between Jimi Hendrix and Massive Attack. It's not really like my dad, but there will always be similarities because we have the same vocal cords, and I learnt the guitar the way he taught me.

One interviewer asked me: 'How do you feel that you've betrayed your father?' That wasn't really very cool.

'Keep your head down at school.' Those are sage words from my dad. They kept me in check for years.

I came home one day from school after being chased by kids singing “Yellow Submarine”, and I didn't understand why. It just seemed surreal: why are they singing that song to me? I came home and I freaked out on my dad: 'Why didn't you tell me you were in The Beatles?' And he said, 'Oh, sorry. Probably should have told you that.'

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 sometimes listen to music I made and find it to be something I wouldn't want to buy from a store, if there was a store. When it's like that, you have to make what you want to hear.
