I only discovered electronic music as a teenager and I still love the Prodigy and Massive Attack.

When my dad toured in '91, I think my first gig properly was the Tokyo Dome, 50,000 people indoors. That was pretty scary. I was 12, or 13.

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.

I was very empty after my father passed away. It was an emotional time, as it would be for anyone, but to be in the studio every day was kind of cathartic and healing and it just seemed very natural to continue.

My dad was my hero, my best friend.

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.'

I was always brutally teased for being George Harrison's son. That was from the age of about four or five, before I even knew who he was. And for seven years people would follow me about school singing 'Yellow Submarine.' I still can't listen to that song to this day.
