"Topsy" is an instrumental by Count Basie and His Orchestra, released on August 9, 1937, written by Edgar Battle and Eddie Durham.[1] It became a #14 pop hit for bandleader Benny Goodman in 1938.[2]
In 1958, drummer Cozy Cole recorded the song and issued it in two parts as a single. The A-side ("Topsy I") made it to #27 on the Billboard Hot 100 chart, while the B-side ("Topsy II") reached #3 on the Hot 100 chart and #1 on the Billboard Rhythm & Blues chart, staying atop the latter for six weeks.[2] The two songs were simultaneous hits; they were closest together on the Hot 100 chart for the week ending November 2, 1958, when Topsy I was at #27 and Topsy II was at #4.[3][better source needed]
