ROADDOG is up at El Golfo again this Thursday night, and here's the math on this show. Give them five dollars for the cover charge, and you get a ticket good for an eight dollar Margarita. (I was never good at numbers, but it's like they give you $3 to have a drink and hear live music.) Plus the band features veteran players including key board master Arif Durrani, and Mike Colburn who can deliver a song like nobody's business. It's a heck of a deal.
