It's strange. At some point in your career, the situation between yourself and the camera reverses. For a certain number of years, you court it and you need it, but ultimately, it needs you more, and it's a bit like a relationship. The minute that happens, it turns you off... and it does feel like it is taking something from you.
I realised those things my ego needed - fame and success - were going to make me terribly unhappy. So I wrenched myself away from that. I had to. I had to walk away from America and say goodbye to the biggest part of my career because I knew, otherwise, my demons would get the better of me.
I had been obsessed with insects and creepy-crawlies: I used to get up at five o'clock in the morning and go out into this field behind our garden and collect insects before everyone else got up, and suddenly, all I wanted to know about was music. It just seemed a very, very strange thing.
The first sign of real obsession with music was with an old wind-up gramophone that mum had thrown out into the garage. My parents gave me three old 45s - two Supremes records and one Tom Jones record - and I used to come home from school literally every day, go out to the garage, wind this thing up, and play them.
