"I was recording stuff with my dad when I was like five, six years old. I played with him on tour. I'd gone with him to Japan in '91, played some gigs, did a couple shows at the Albert Hall."

"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.'"
