Viva Las Vegas was a extended play record by Elvis Presley,
containing four songs from the 1964 motion picture, Viva Las Vegas.
It was released by RCA Victor in May 1964.
In 1993, it was released as part of the RCA "Double Feautes"
remastered CD collection. This edition had all the twelve songs and
11 of the Roustabout soundtrack.
In January 2010, as part of the 75th anniversary of Presley's birth,
Sony Music finally released an official almost-complete soundtrack
album for the first time on CD, which includes all twelve songs
recorded for the film. The front cover of the CD insert reproduces
the images used for the original EP release, and also adds the words
"...AND MORE" as part of the text. The release was not a complete
soundtrack, as it omitted the film version of "C'mon Everybody", the
duet version of "Today, Tomorrow and Forever" and "The Climb"
featuring Presley on backing vocals. It also excludes the songs with
Ann-Margret on lead vocals, "My Rival" and "Appreciation". (wikipedia
