My Shining Hour is a standard composed by Harold Arlen with lyrics by Johnny Mercer for the 1943 RKO film The Sky's the Limit, starring Fred Astaire. In the film, Sally Sweetland dubbed the vocals for actress Joan Leslie, accompanied by Freddie Slack and his Orchestra. The song's title is thought to reference Winston Churchill's famous "finest hour" speech, capturing the patriotic spirit of the wartime era. Nominated for the Academy Award for Best Song, it lost to "You'll Never Know." The first commercial recording by Glen Gray and the Casa Loma Orchestra, featuring vocalist Eugenie Baird, reached No. 4 on Billboard's Best Selling Retail Records chart in 1944. The tune shares its film origins with another enduring Arlen-Mercer collaboration, "One for My Baby (And One More for the Road)." Built on a melody of predominantly quarter notes and half notes within a relatively narrow range, the composition lends itself naturally to brisk tempos while remaining adaptable across diverse settings. It has been recorded over 260 times by both vocalists and instrumentalists. Ella Fitzgerald's version on the Harold Arlen Songbook is notable for including the rarely performed 12-bar verse. John Coltrane's 1961 recording became a touchstone for saxophonists, and Frank Sinatra, Andre Previn, and Peggy Lee each brought distinctive interpretations to the song.
