Many of us grew up with Colin Quinn as a member of Saturday Night Live, but there are those of us whose first dose of Mr. Quinn’s raspy Brooklyn accent was on MTV’s non-gameshow, “Remote Control,” where he’d destroy the hits of the year in his unmusical voice. Since then, this stand-up comedian has acted in films and television, hosted comedy variety shows, and recently popped up on an episode of “Girls.” But during his stint on SNL, Mr. Quinn was already working on long-form stand-up. His first show, “Colin Quinn: An Irish Wake” went to Broadway, and since then, he’s maintained a presence on stage. Now this Saturday, he comes to the Lobero with his latest, “Unconstitutional,” an examination of our nation’s founding document, or 226 years in 70 minutes. This will not be a history lesson, but you just might learn something … and you will be laughing. In this interview, however, Quinn gets into the serious business of parsing this document and reveals that he’s a big James Madison fan.
