swizzle schtick

Does anyone know anything about Doc Scantlin and His Imperial Palms Orchestra, specifically their "Swizzle" supper club performances at the Ronald Reagan Building? From their web site, and given that they've performed at such high-society weddings as that of Madeleine Albright's daughter, and of Alexandra Miller and Alexander von Furstenburg, they sound fun but potentially very straight, in which case I'm not sure we'd want to spend the money to go (e.g., if we'd have to sit out the dancing). But at the same time they're advertising in the Washington Blade each week, so I'm wondering if the crowd tends to be pretty gay-friendly. If so, it sounds like it could be a lot of fun for Jeff and me to do as a special night out of dinner and dancing to a big-band sound.
