In 1978, the Broadway musical and tribute to Fats Waller, Ain't Misbehavin', received a Tony Award as Best Broadway Musical.
It remains one of five jazz standards written by Fats Waller that is still played by stride pianists and students of ragtime in the 21st century. The Louis Armstrong rendition of Ain't Misbehavin''' also inspired Ella Fitzgerald's sense of phrasing, rhythm, delivery, and even choice of songs.
