Show tunes and gay men, of course, go together like Rodgers and Hammerstein, and the Sunday night event draws a stereotypically gay crowd – if by stereotypical you mean a white, tall, butch, flamboyant, single, married, black, loud, shy, tone-deaf, operatic, Hispanic, leather-jacketed, polo-shirt-wearing, elderly, 20-something gay crowd. “Oh, What a Beautiful Mornin’,” from “Oklahoma,” is a fixture at Bolt Video Bar’s show tune night, although the musical is more commonly referred to as “Oklahomo” in this setting. It’s Sunday night at the Bolt bar in Minneapolis, and the corn is as high as an elephant’s eye.
