You have to be original. The people creating a buzz on YouTube are taking risks, and they're doing something different. I like it when 15 year-olds come on and tell me what to do rather than the other way around.

The biggest shock when I lost it all was the realization that so much of my life had been out of my control. When I started to make the money back, I vowed that it would never happen again. I bought things only when I could afford them. There was no big mortgage, no cars on hire purchase. I remember buying a TR6 sports car for £6,000, and funnily enough it gave me more pleasure than the Porsche ever had.

I honestly can't ever imagine retiring because I don't know what else I would do - even when I'm on holiday, 70% of the time I'm working. I think I'd like to go out on the job so, ideally, 'And the winner is... Ooooh, and he's gone!'

The artists who endure are the ones who stay focused even after they have reached the top of their profession.

I've spent hundreds of thousands of pounds on the very best security and I can assure you my homes are as safe as the Bank of England.

I don't mind competition at all. I mean, the record business is the most competitive business in the world, probably. So I'm used to that. In a weird way, it kind of makes you work harder.

I think the best singers in the world, historically, are American. Britain's got its fair share, as well, but some of the greatest singers, ever, whether you're talking about Whitney Houston or Mariah Carey or Aretha Franklin, are from the legacy here.
