'I think the thing that Madonna does, which I hope I can do, is that she has this ability to come across as quite austere at the beginning :not cold exactly but a little detached. But at the end of it she looks like she's having a great time - she's dancing, and you're dancing, and it's all great. I think that's really clever how she gets that dynamic to work. You always feel at the end of it that you've somehow won her over. I don't know, that's a real:you know what I mean? Not everyone has that.'
