One of the most eccentric vocalists ever to hit the jazz scene, Slim Gaillard became a legendary cult figure thanks to his own privately invented jive dialect "vout," a variation on hipster slang composed of imaginary nonsense words ("oreenie" and "oroonie" being two other examples). Gaillard's comic performances, laid-back cool, and supremely silly songs made him a popular entertainer from the late '30s to the early '50s, especially on the West Coast, and several of his compositions became genuine hits, including "Flat Foot Floogie" and "Cement Mixer." Versatility was not Gaillard's stock-in-trade, but he was highly effective at what he did, and his musical ability as a singer, Charlie Christian-style guitarist, and boogie-woogie pianist was perhaps a bit overlooked in comparison to the novelty value of his music. Slim was born Bulee Gaillard, most likely on January 4, 1916 in Detroit, MI; some sources list his birth date as January 1, and Gaillard sometimes claimed to have been born in Santa Clara, Cuba, instead of Detroit. His father worked as a steward on a cruise liner, and sometimes brought young Slim along, once accidentally leaving him behind on the island of Crete. Gaillard was mostly raised in Detroit, though, where he tried his hand at professional boxing, worked as a mortician, and ran bootleg rum for the Purple Gang during the '30s. He also developed an act in which he played guitar and tap danced simultaneously, and eventually moved to New York to work the vaudeville circuit. In 1936, he teamed up with bassist Slam Stewart as Slim & Slam, and two years later they scored a substantial hit with "Flat Foot Floogie," which was quickly covered by the likes of Benny Goodman and Fats Waller in the wake of the original recording's success.
