The Soundies #12

This is a movie scene from the soundie era.  A couple of years ago, I was a captive audience for the film Hellzapoppin' (1941).  Ole Olson and Chic Johnson are not funny at all, and I wasn't expecting this pleasant surprise.  The scene starts with Slim and Slam—Slim Gaillard on piano and Slam Stewart on bass—who had a hit with "Flat Foot Floogie" in 1938.  They are joined by Rex Stewart, trumpet; Jap Jones, trombone; Elmer Fane, clarinet; and C. P. Jonstone (or Johnson), drums.  The dancers are the Harlem Congeroos.  One of the songs listed on the soundtrack is called "Congeroo," so this is probably it.
