"Are You Lonesome Tonight?" #1 12/3/1960

Originally written in 1926, this was the favorite song of Col. Tom Parker's wife, so the Colonel personally asked Elvis to record it as soon as he got out of the Army in the spring of 1960. RCA didn't release the song right away, however, fearing it was out of character for the King. When they finally got around to doing so, it stayed at #1 for six weeks. There is a "laughing Elvis" version from a 1979 box set where he just loses it on stage. Happens to the best of them.
