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.

Nice to see you, to see you nice

It's sad when you see most of your friends in the business gone, like Tommy Cooper, Frankie Howard, Eric Morecambe, Roy Castle, Les Dawson. They were very dear to me. You no longer have the chance to bump into them at a celebrity do.

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.

It's the combination of marrying a beautiful woman three decades younger and my iPad that keeps me young.

If I couldn't move, I don't know what I would do. That would be terrifying for me; I don't know how I'd cope with that.

When I was in the business as a young performer, it was a recognised fact that when you got to 60 you were out, because there'd be a new crop of comics coming up all the time, every 10 years or so.
