From the wiki: “‘At Last’ was first recorded in 1941 by Glenn Miller for possible inclusion in the film Sun Valley Serenade. The song, sung by Pat Friday with actor John Payne, was going to be a major performance on the soundtrack. But, the song was mostly deleted from the release print.
“A subsequent recording, in 1942, was made and used extensively a follow-up movie, Orchestra Wives (1942), with vocals by Pat Friday (dubbing for actress Lynn Bari) and Ray Eberle. In 1942, a vocal version of ‘At Last,’ sung solo by Ray Eberle, was recorded for commercial release by Glenn Miller and His Orchestra in Chicago in May 1942 and first released as the B-side to ‘(I’ve Got a Gal In) Kalamazoo’.
“Former Glenn Miller Orchestra trumpeter Ray Anthony had the highest charting recording of the song in the U.S. on the Pop charts in 1952, peaking at #2 on the Billboard Music Popularity Chart. In 1961, ‘At Last’ became Etta James’ signature song and was the third in a string of successful songs from her Chess Records debut album At Last!. In April 1961, it became her second #2 R&B hit and crossed over to pop radio, reaching #47 on the Billboard Hot 100. James’ recording was inducted into the Grammy Hall of Fame in 1999.”
