Growing up in inner-city Glasgow, it sometimes seemed to me money hadn't been invented.

I've always had money because of my early success with Cream, so I tell young musicians to aim to write their own material, because owning the composition rights makes a very big difference.

I think I'm an okay parent, but I'd put myself in the category of a musician-who-happened-to-become-a-father. I'm definitely not a father-who-happened-to-be-a-musician.

Thankfully I'm not endlessly ambitious, but I have done some crazy ambitious things like buying an island off the west coast of Scotland in the late Sixties.

I did the Kilimanjaro climb a few years ago, then the six-day trek to Machu Picchu in Peru so this bike ride to raise money for Great Ormond Street seemed like the next big challenge.

No professional athlete likes to admit that he has played too long. There is too much money involved, rarely enough saved, and there is the eternal hope that age has not withered skills.

From the age of seven, I knew I wanted to play football - I didn't think about it in a professional sense in terms of making money from it; it was more about the social aspect of being with my friends and losing myself in the sport.

Ability is a poor man's wealth.
