Fats Waller recorded Sugar at the RCA Camden Studios on February 16, 1927. The building had once been the Trinity First Baptist Church and the organ had been to perform sacred music during church services. Sugar was composed in 1926 by Maceo Pinkard, lyrics by Edna Alexcander and Sidney Mitchell. For the songs he wrote, Maceo Pinkard should be much better known. His most famous composition was Sweet Georgia Brown, which was famous as the theme song for the Harlem Globetrotters Basketball Team.
