Who you gonna call for your next vodka on the rocks? Dan Aykroyd, of course. The Ghostbusters and SNL veteran drew a thirsty crowd to Stache 1920's Drinking Den Friday, March 20 while promoting his top-shelf Crystal Head Vodka. After signing and swigging a few, Aykroyd revisited his days as Elwood Blues, joining South Florida's Blues Brothers Soul Band for a performance on stage.
