I involve myself in an organisation called Tear Fund.

It's important to put all I have into my career.

Of course, when I started my career, like anyone else who was 16 at the time, we were besotted by the rock-n-roll scene from America, and all I was interested in was having a career of my own.

I liked the Beatles but I wasn't mad on the Stones. I always thought they were a slight rip-off of Chuck Berry and some of the old blues people, and they never seemed to change. If people compare me to Jagger and the Stones I would be the one to be put down ... I've been far more progressive than any of them.

But Portugal has a peaceful feel about it. I sit on the terrace overlooking the vineyard there and I feel cut off from the world. You need that sort of thing.

If I'm going to represent God I have to do it the best I can.

When you're out there with thousands of people it's probably better to have a bigger show to look at, and it turned out really well and they videoed it for me.
