Chappie Willett contributed a chart for the Krupa band's band book named "Rhythm Jam." Sam Donahue takes a few exciting licks on tenor sax before the band takes over on one of the first dates by the Krupa band on July 19, 1938. After a brief intro by pianist Milt Raskin, tenor saxist Sam Donahue comes back for another clean, crisp swinging rendition. Corky Cornelius sails by with a great trumpet solo with single note exhortations high up on his instrument before leading the band through a romping coda with Krupa swinging away at the drums.
