Two smooth-talking producers are trying to raise money for their musical review. They line up a potential backer who will put up half the cash if they can find someone else to co-finance the production. The duo enlist the services of a cigar-smoking cross-dresser named "Bumpsie" (Tim Moore), who poses as the wealthy "Madame Deborah" to fool the backer. Their scheme goes smoothly - until the real Madame shows up! Madness and mayhem mix with jam sessions at a Harlem roof party where legendary drummer Gene Krupa performs a surprise drum solo. Famous black entertainers include Big Sid Catlett and his band, The Slam Stewart Trio, Deek Watson and The Brown Dots, and The International Jitterbugs.
Tim Moore is known to millions of fans as George "Kingfish" Stevens, of the extremely popular "Amos 'n' Andy" television show (1951-1953). He played in musical revues on Broadway and in Europe before embarking on a movie career that includes His Great Chance (1923) and Darktown Revue (1931). Moore had already retired from 50 years of performing when he was cast as "Kingfish."
