According to Crazy From The Heat, his uncle owns Cafe Wha? on..what, Macdougal St? This is more like a Diamond Dave triva thread than a Help Margot thread. But Margot, if you DO meet him please tell me everything.
He lives a few doors down from the old Collective Unconcious on Ludlow. I think he lives at the corner of Rivington and Ludlow. Aparently he is indeed going for his EMT liscense.
