It Must Be Jelly ('Cause Jam Don't Shake like That)
"It Must Be Jelly ('Cause Jam Don't Shake Like That)" is a 1942 jazz and pop song recorded by Glenn Miller and His Orchestra. The song was released as an RCA 78 single by Glenn Miller.
The music was written by Chummy MacGregor and George Williams and the lyrics by Sunny Skylar. George Williams also arranged the song. A version was also recorded by the Army Air Force band under Glenn Miller.
The Glenn Miller civilian band played the same arrangement that was performed at least twice, available on a Victor 78 recording, Victor 20-1546-A, recorded July 15, 1942. There is also a version taken from a radio remote broadcast from September 15, 1942 in Boston, Massachusetts and later re-released by RCA Victor on LPT 6700.
The 78 single, Victor 20-1546, reached number twelve on the Billboard charts in January, 1944, where it stayed for eight weeks on the charts. Moreover, the record was a crossover hit, reaching number two on the Billboard 'Harlem' Hit Parade Chart on February 19, 1944, the then equivalent of the later R&B chart, and number sixteen on the Billboard Juke Box Chart.
Harry James, Johnny Long, Back Alley Hoodoo, and Frankie Ford also recorded versions. Woody Herman recorded a version that was also released as a V-Disc, No. 320B, in November, 1944. Ray McKinley performed the song with the Glenn Miller Orchestra.
