"Viva Las Vegas" is a 1963 song written by Doc Pomus and Mort Shuman and recorded that same year by Elvis Presley for his Viva Las Vegas film vehicle, which along with the song was set for general release the year after. Although Presley never sang the song live, it has since become widely known and often performed by others. The RIAA on March 27, 1992 certified it gold having sold in the United States 500,000 copies.
Released as the b-side of the "What'd I Say" single from the same film, "Viva Las Vegas" charted separately from its A-side, a modest hit reaching #29 on the Billboard Hot 100 pop singles chart. The Elvis version of "What'd I Say" peaked at #21, the two sides having equivalent appeal in the marketplace. "Viva Las Vegas" reached #12 on the UK Singles Chart, improving to #15 after a reissue in 2007. It is noticeable on the recording that Presley erroneously sings 'Los Vegas' instead of 'Las Vegas', which detracts not only from the placename itself but suggests that Presley did not have personal knowledge of the correct pronunciation of the said location of the film, or was not corrected in the recording of the track. In the years since its first release, the song has become one of Presley's most recognized numbers. In the 1990s and 2000s, the song appeared in countless movies and TV sitcoms, either as a reference to the city of Las Vegas, or simply as an expression of joy or bewilderment in related comedic situations.
In 2002, the city of Las Vegas requested Elvis Presley Enterprises, the company that handles a portion of Elvis's legacy and all Elvis-related music rights, to allow it to be the official song of the city. Negotiations stalled over the price requested by EPE, notwithstanding that EPE had not controlled the copyright to the song since 1993, at which time it became the property of the families of the songwriters Doc Pomus and Mort Shuman. Since EPE no longer owns the copyright to the song, it essentially means that EPE does not have the authority or right to negotiate the use of the song "Viva Las Vegas" within the United States, its territories and possessions, although EPE may be able to negotiate the use of the actual Elvis recording of the song.
The song is featured in the film The Big Lebowski (1998). Shawn Colvin performs it as a folk ballad during the closing credits. A rock version in the film is credited to a band called Big Johnson, and is styled after the ZZ Top version. The Colvin version was recorded originally for the Rhino/Forward release, Til the Night is Gone: A Tribute to Songwriter Doc Pomus (1995), and is also featured prominently in Episode 11 of Twin Peaks.
The song is a part of Bruce Springsteen's live act, and was included in The Last Temptation of Elvis, a commemorative album of renditions by singers, and rock groups, of songs made famous by Presley. Springsteen's studio version of "Viva Las Vegas" was also included in the soundtrack of the film Honeymoon in Vegas (1992), and in his compilation The Essential Bruce Springsteen (2003).
