One of the strangest experiences one can have is to sleep on stage, as I once did in Sydney when I'd lost the key to my flat. I had to stay at night in a bed, which conveniently was on stage because my character Sandy Stone did his monologue from a bed. To wake up looking at a shadowy auditorium is a very peculiar feeling.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
