We wrote 'Stellify' for Rihanna, but as we got to the end of writing it, I thought, 'You know what? I'm gonna keep this for myself. We'll give her another one.' She'd have probably sung it better, but it is too good for me not to do it.
I went to a friend's 40th in Manchester, and there was a karaoke machine, and no one was having a go. My mate said, 'No one's singing because you're in the room.' I said, 'Who am I, Frank Sinatra?' They made me sing flipping 'My Star' to a backing track that sounded like '80s Roxy Music. It was pretty embarrassing, but I did it.
When I was 9, I was into T. Rex, Gary Glitter, and Alice Cooper. I knew The Beatles because my nan introduced me to them, but T. Rex was the first band I got into myself. I got 'Metal Guru' a few months after hearing 'Children of the Revolution' in Pwllheli in North Wales at a market.
I was skint, and I had to move back to my mum and dad's house, back into the room I shared with my brother when I was a kid. I kept getting people on the streets telling me that they loved me; it didn't mean anything to me because I was still borrowing tenners off my pensioner father to go and get some chicken.
It is a fact that everyone's got a limited run in music - but who's to say how long that run lasts? I used to think that there would be no way I'd still be in music when I was 40. I used to think anyone who was 40 was an old man, and they probably shouldn't be doing it anymore.
I gave it up three weeks before my black belt, foolishly. I got to my third brown belt and must have trained for 18 months but never went for it. I was nearly 18 and got this thing in my head about, ' Who are they to grade me?' Trying to be a rebel when I should have done it. It's my only regret, not going for a black belt.
