Friday, May 9 at 9 pm the fun begins, and lasts until 6 am on Saturday. We’re not sure whether this year’s theme is a promise or a threat to male dancers. After all, they will have to do a LOT of leading (i.e., thinking), as well as moving, during the couples dances, which all experienced male dancers can attest is very tiring. In any case, this will be the 21^st year that Stanford’s amazing Richard Powers has led this event, and doubtless at 6 am there will be a lot of dancers who are 10+ year veterans.
