Jim - the aerobics was a long time ago and the person in question did it, suddenly, in front of a platform full of people waiting for the train to London which was late. If she thought they were going to join in she was sadly mistaken - she ended up with a solo performance and a red face, while we all pretended we weren't with her.
Sorry my rain dance didn't work Taz and you still had to be out in the elements x
