You've got to have this burning desire in your chest to succeed.
I am passionate about football. My support for Celtic FC has got me through some hard times in my life. I still play regularly, too.
I enjoyed the chase.
A show is like having a climax. It's like having an incredible, natural climax. And then suddenly it's all finished, and you don't know what to do next.
Listen, if my career was to end tomorrow, I would have no complaints whatsoever.
I am a man of contradictions, I suppose.
I hated singing and getting up in front of crowds.
I deliberate over the lyrics; I really do. I'll come up with one line in a day, and then it might be a couple of days before I come up with the rhyming line. It's never been easy for me.
I'm just delighted that this woman I love can be a mum again.
It was early detection that saved my voice - and I imagine, my life.
I want to make people aware of early detection.
Elvis was the king. No doubt about it. People like myself, Mick Jagger and all the others only followed in his footsteps.
I think I was always looking for that perfect woman, who obviously doesn't exist. I wanted to be married. I wanted more kids. I'm a family man, at heart.
Fast cars like Porsches and Ferraris - they are things of beauty.
I can definitely say the older I've got the better I've become at being a dad and a husband.
At my age you don't go into fatherhood lightly.
My father, being a Scotsman, taught me to look after finances. I'm shrewd. Some people may call me tight.
Instead of getting married again, I'm going to find a woman I don't like and just give her a house.
I have lived a great life. I am very happy.
You can avoid the press if you really want to and I don't walk around with five security guards either because I think that just draws attention.
