When a performer doesn't get nervous, that is when you have to give up.

It's important for a dancer to wear very tight underpants. I used to feel a bit exposed if I wasn't being held up in the right place.

I met my darling wife Wilnelia in 1980 when we were on the judging panel for the Miss World contest at the Royal Albert Hall. With two ex-wives and five daughters, I thought I wouldn't be involved with anyone for a long time - if ever. Winnie was so gorgeous, my jaw dropped - and it's a big jaw to drop.

No one - apart from my agent, perhaps - should leave one of my shows in tears.

All kids love to get dirty, but if I wandered into the garage, my father would say: 'Son, you're not going to have filthy hands like mine. You're going into show business.'

Goodness, that Simon Cowell is a sensitive soul.

Once you've experienced the warmth of an audience, the achievement of getting your first laugh, and entertaining them, singing or playing piano, it just keeps it all going.
