When It Rains, It Really Pours is a song originally written and recorded by Billy "The Kid" Emerson. His version, titled "When It Rains It Pours", was released by Sun Records in 1954. The song was later recorded by Elvis Presley in 1957, but not released until 1965 on the album Elvis for Everyone.
Presley had initially attempted to record the song while at Sun Records in November 1955, but it was never completed as his contract with Sun was sold to RCA Records around the same time. The tapes of all Presley's Sun recordings were handed to RCA as part of the deal, with most of them being included on albums released shortly afterwards. Presley's 1955 recording of "When It Rains, It Really Pours", however, was not released. It was lost for several years until 1982 when it was found and finally released officially on the 1983 compilation album Elvis: A Legendary Performer Volume 4.
On February 24, 1957 Presley again recorded the song, this time for RCA. This version also went unreleased until it appeared on the 1965 albumElvis for Everyone.
In 1968, during rehearsals for the television special Elvis, Presley was recorded singing it as a potential song for the show. Although the song was not chosen for the special, the rehearsal was released on The Complete '68 Comeback Special CD released in 2008.
