If the door’s locked at Vaughan’s Lounge, ring the buzzer – someone will let you in. Any night but Thursday, Vaughan’s is a rundown neighbourhood dive with the charms of a speakeasy. Young hipsters wander in to shoot pool and drink cheap beer. On Thursdays, however, jazzman Kermit Ruffins and his Barbecue Swingers hold court. With a swaggering style and a mission to make people dance, Ruffins plays like the reincarnation of Louis Armstrong. A sweaty crowd of young and old, black and white, crams into Vaughan’s, singing along and shaking to the beat until the band goes home. Get there early to sample Ruffins’ barbecue, which he cooks on a grill that he keeps in the back of his truck.
