They do say, the smaller the feet, the better the dancer.

Little did I know that there's nothing more competitive in the world than a professional ballroom dancer. They are as competitive as Olympic athletes.

I've always been a family entertainer. Every show I have done has been suitable for any age - parents never need to worry that, if they pop out of the room, I'll say anything untoward.

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.'

My biggest regret is that my mother didn't see me walk on to that London Palladium stage, being the star she always wanted me to be. But I always say that when she reached Heaven, she had a word with a few agents.

When you've been brought up in variety, I think timing is always important in your life. If I'm ever late for anything, whether it's personal or business, I always apologise. 'I'm sorry I'm late,' and all that. And if somebody is late meeting me, I expect them to say 'I'm sorry I'm late.' It's just, shall we say, showbiz etiquette of my day.
