"I used to joke that one of the reasons there was a lack of classical work on my CV was because I couldn't operate in those kinds of trousers. Which is a joke, but it's actually also true - if I want to appear in public I want to look my best. If I'm onstage I like to do contemporary work, largely because of the trousers, because of the clothes. I like a decent, what we used to call a lounge suit. Then I can start to motor."
