I'm Gonna Sit Right Down and Write Myself a Letter is a 1935 popular song with music by Fred E. Ahlert and lyrics by Joe Young, introduced by Fats Waller & His Rhythm. It was released as a Victor single on May 29, 1935 and, while not tied to a specific album at first, has become a standard of the Great American Songbook and is linked to the Harlem Renaissance era and the Broadway show Ain't Misbehavin'. The playful lyrics tell of a singer who plans to write a letter and pretend it is a love note from the beloved. The tune has been recorded many times, including Frank Sinatra on the 1954 album Swing Easy, Bing Crosby on Bing with a Beat (1957), a 1957 Coral hit version by Billy Williams, and more recently Paul McCartney on Kisses on the Bottom (2012).
