What's the difference between drama and theatre?

Guardian Unlimited: "The playwright Edward Bond raised a few eyebrows recently by, among other things, dubbing Brecht 'the playwright of Auschwitz'. His argument was so patently absurd that I barely hiccuped. Instead, another statement caught my eye. Bond was speaking of a production of his play The Woman, which he directed at the National: 'I went back to see it after it had been playing for a week and the actors were doing it as if it were Tom Stoppard. They were doing 'theatre'. But drama is not 'theatre'.' You could almost hear his disgust."
