“I used to have to beg and borrow £25 to hire some French windows. I started prod…” — Cameron Mackintosh

My aunt took me to see 'Salad Days' when I was seven. This story of a magic piano that infects everyone who hears it infected me, too. It was a Road to Damascus moment in my life.

I think the worst thing that could have happened to me would have been having a hit at 20. I don't know what that would have done to me. But instead, I had to scrape a living for years. And my first show, which opened in 1969, lost over £45,000, an absolute fortune then.

I don't commit to things unless I have my A-team to do it. And I'm not trying to be cocky, but that shows in my productions. They are top notch!

By the time I was ten, everyone knew I wanted to be a producer. I was a very precocious little boy.
