I knew nothing about film at all. I suppose the biggest surprise is all these things. In the theatre we sort of do, I might do two or three key interviews and that would be it.

The fact is that 'The Wizard Of Oz' has never really worked in the theatre. The film has one or two holes where, in the theatre, you need a song. For example, there's nothing for either of the two witches to sing.

The one thing I have always felt about musical theatre is that it is, to an extraordinary degree, about construction.

Musical theatre history is littered with bad reviews for now classic pieces.

It must have been an extraordinary time. I guess the worrying thing about musical theatre to me, is if you look at the London season this year, mine is actually the only one to have come in.

I never wanted to be a performer. I suppose I was precocious, really.
