I like classes as icebreakers on freestyles. I accept that many of the people on the forum are 'hardened'

dancers, and don't need help to get loosened, some of the newbies do and a short sharp fun class can do this.
For instance at the Jive Nites Spring Ball Adam and Tas taught a fun class about an hour into the night. By the time they'd finished everyone was laughing and the party mood had been well and truly cemented. They taught a swing class - and we were dancing MJ so it was not about teaching but all about getting people into the right mood.
