Tonight I Shall Sleep (With a Smile on My Face) is a song with music by Duke Ellington and lyrics by Irving Gordon, sung in English. SecondHandSongs also credits Mercer Ellington as a writer. The first recording was made on 4 June 1945 by Tommy Dorsey with Duke Ellington and His Famous Orchestra. It was issued as a 78 rpm single, with "The Minor Goes Muggin'" on the reverse side.
The song is a ballad in a jazz idiom and is regarded as a jazz standard. It has been recorded by many artists, among them Albert Hibbler and Sarah Vaughan (both in 1949), Stan Getz (1966), Zoot Sims (1980), Scott Hamilton (1990) and Harry Allen (2003). Its recordings thus span more than five decades, from the original 1945 version to versions made well after the song's first release.
