I went to a Grease singalong with a friend and had lots of fun. The crowd was a bit dead, and nobody dressed up so it wasn't quite as special as I imagined. I was wearing blue jeans and a white tshirt with a black bomber jacket, and I was doing better than anyone else.
I want to go with more people next year, so that we can all roll in wearing leather jackets over tshirts and high-waist jeans. It would be cool to try to get people up to dance during the Hand Jive scene, and just generally...
