[Callers] Wanna teach polka (and maybe call one dance) at Harvard Divinity School next Friday afternoon for free?

Boston-Area callers: Harvard Divinity School has an annual Oktoberfest where a professor's German band plays mostly polkas for two hours. I have a dancing friend from California now attending HDS, and she's bummed that nobody knows how to polka so there's never any dancing, and is hoping to scare up somebody who can come and give a quick lesson to give people confidence to get up and dance. (I asked if that person could maybe lead a country dance to polka music too and she says fine.) There's no funding, so the pay is in beer, sausages, pretzels, and karma. It's on the Harvard Campus, October 19. The whole event is 3-5 pm, and I assume a half-hour polka lesson is most useful at the beginning. If interested get in touch with me and I'll pass your info on to my friend. Thanks! -- Alan
