From the wiki: “‘Harlem Nocturne’ was written by Earle Hagen and Dick Rogers in 1939. The song was adopted by bandleader Randy Brooks the next year as his theme song, but was first recorded in 1939 by Ray Anthony & His Orchestra. Hagen was a trombonist in Ray Noble’s band at the time. He had been inspired by Duke Ellington’s saxophone player Johnny Hodges and wrote ‘Harlem Nocturne’ for Noble’s sax man Jack Dumont, originally titling it ‘Duke’s Soup’. The name change was suggested by the publisher.
