Named after the song by Fats Waller, the musical is a tribute to the black musicians of the 1920s and 1930s who were part of the Harlem Renaissance, an era of growing creativity, cultural awareness and ethnic pride. It was a time when Manhattan nightclubs like the Cotton Club and the Savoy Ballroom were the playgrounds of high society and Lenox Avenue dives were filled with piano players banging out the new beat known as swing.
