It was recorded by Wayne King and his Orchestra with vocal by Ernie Birchill on February 18, 1931 and released by Victor Records as catalogue number 22643. It was a top 20 hit for Frankie Laine in 1950. Later notably sung by Doris Day (who, in 1957, was the first singer to record it at the slow tempo in which it had been written), Louis Armstrong and Ella Fitzgerald. It is arguably best known for the rendition by “Mama” Cass Elliot of The Mamas & the Papas, in 1968, which sold 7 million copies.
I personally think this works very well for the ukulele - its a slow chilled piece. Bring back the sunshine so I can get out the ol’ hammock to play this in! I’ve found it works better to play the last note as the A chord instead of just the note on the end.
