In 1935, Morton moved to Washington, D.C. to become the manager and piano player at a bar called, at various times, the Music Box, Blue Moon Inn, and Jungle Inn, in Shaw, an African-American neighborhood. Morton was master of ceremonies, bouncer, and bartender. The club owner allowed her friends free admission and drinks, which prevented Morton from making the business a success. During Morton's brief residency at the Music Box, the folklorist Alan Lomax heard him play. In May 1938, Lomax invited Morton to record music and interviews for the Library of Congress. The sessions were intended to be a short interview with musical examples for researchers at the Library of Congress, but the sessions expanded to over eight hours, with Morton talking and playing piano. Lomax conducted longer interviews, taking notes but not recording. Lomax was interested in Morton's days in Storyville, New Orleans, and the ribald songs of the time. Although reluctant to record these, Morton obliged Lomax. Because of the suggestive nature of the songs, some of the Library of Congress recordings were not released until 2005.
