As a 29-year-old, the only thing that I can possibly think is that if I'm still performing at 50, it's because I'll have had disastrous marriages and I have to pay for them.

There used to be a huge hole in my life that I wrote many albums about. I didn't realise it was a wife-and-daughter-shaped hole. They've plugged that gap. Everything I do, I do for them now. When daddy goes to work, it's daddy going to work, not Rob going to work. I feel like there's a purpose to everything.

I come from the tradition of a big Irish family that loves to sing. I love to perform.

When Daddy goes to work, there's a mouth to feed, a point to life and a reason to do things

Some of the best times in my life happened under the influence of drugs... I'd still be doing it if I could make good judgement calls. I'd still be doing it if I didn't blow up to the size of an aircraft hangar, because it was a great time.

I am the only man who can say he's been in Take That and at least two members of the Spice Girls.

It's success, not fame, that is quite addictive. I'm addicted to a lot of things and, as it happens, success is one of them.
