The soundtrack songs were recorded in July of 1963 at Radio Recorders Studios in Hollywood, California and are regarded by some as among Presley's best. In addition to Presley's vocals, Ann-Margret performs two solos in the film. Three songs, "Night Life", "Do The Vega" and "You're The Boss", were recorded for the film but never used. "You're The Boss" is a duet by Elvis and Ann-Margret.
RCA Records has been heavily criticized (in Elvis: The Illustrated Record and other retrospectives) for mishandling what was considered by critics to be the best set of songs recorded for an Elvis film for years. None of the vocals involving Ann-Margret was released at the time, although she was a successful RCA recording artist in her own right and had performed two solo numbers in the film ("Appreciation" and "My Rival"). The only recordings released simultaneously with the film were the theme song plus a cover version of "What'd I Say?" on a single; and a few additional songs on an EP entitled Viva Las Vegas, even though the title track was not included. Additional songs recorded for the film would appear scattered about later album compilations, while the Ann-Margret duets with Presley - "The Lady Loves Me", the deleted "You're the Boss", and an unused version of the ballad "Today, Tomorrow and Forever" - would not be officially released until long after Presley's death (the ballad would not be released until 2002). The version of "C'mon Everybody" released on record is a different version than the one used in the film, lacking Ann-Margret's backing vocals, a whistling interlude, and the closing bars.
Although bootleg LP's began to appear in the 1970s, purporting to contain the complete soundtrack, RCA did not officially release anything approaching a full soundtrack until 1993, when it began to reissue Presley's film soundtracks on a series of "Double Features" CDs, the pairing of Viva Las Vegas soundtrack with that of Roustabout being in the first batch. These CDs do not include the solo Ann-Margret performances or "The Climb" by the The Forte' Four. An almost complete soundtrack from the film was released on Follow That Dream Records (the Danish division of BMG) in 2003. It includes all master takes plus alternate versions. "The Climb" is also included, but the Ann-Margret solo tracks are not. At present, the Ann-Margret solos are available only on the 5-CD box set: Ann Margret 1961-1966 from Bear Family Records in Germany, but her "You're the Boss" duet with Elvis is on her otherwise solo cd album, "Lovely Ann-Margret: Hits and Rarities," digitally remastered and released 1995 by Marginal Records MA 022, Brussels, Belgium.
According to Elvis historian Steve Pond, in an interview for Kingdom : Elvis in Vegas, a featurette included with the 2007 DVD release of the film, only the lead singer of the Forte Four was actually recorded singing "The Climb", not the rest of his group. Instead, the backing vocals were provided by the Jordanaires and by Elvis Presley himself.
Ann-Margret met Elvis Presley on the MGM soundstage when the two filmed Viva Las Vegas.
They began a one-year affair that received considerable attention from the gossip columnists.
The reports led to a showdown with Priscilla Presley, described by Priscilla in her 1985 book, Elvis and Me, including a discussion of Ann-Margret's attempt to "cut her off at the pass" with a press announcement that she and Elvis were engaged to be married.
Ann-Margret states that although they discussed marriage, they were never engaged and they both knew that the affair would run its course.
Comparisons of Ann-Margret as the "female Elvis" were not confined to the publicity agencies.
The two of them were truly similar in many ways--both were quiet and shy offstage and electric onstage, both treasured their families and believed strongly in God, both loved speed and motorcycles, both could be defiant of danger, and both could be self-destructive at times.
After the affair ended, Presley remained a very close friend and continued to send Ann-Margret flowers at the opening of each of her stage appearances.
4:15 shows the actual pool-lobby interior of the Flamingo.
4:59 shows the Flamingo pool once again and Ann in the inevitable red bathing suit and mandated rear-view-walk-away-shot -
as Elvis enters the picture (now suddenly) working as a costumed waiter for the hotel.
There are some very good views of Vegas swimming pool life until 7:00.
The location shifts and Ann is then seen in black leotards at the UNLV gym doing various early-Sixties gyrations.
She finishes her dance with some subliminally provocative "haw, haw, haws"
and taunts Elvis with the standard Elvis-movie-line: "Are you gonna chicken-out? The kids are expecting you to do something".
He reluctantly agrees with the counter-phrase order "but then we cut-out".
Elvis leads "the kids" into a finger-snapping, hand-clapping, hip-shaking romp with his "C'Mon Everybody" song and camera shots of Ann-Margret, now shaking her bootie to the words "my baby loves me".
4. The last segment of Viva shows the car race, which shows the obligatory car crashes and great night and day views of Downtown's Fremont Street.
Scenes of Lake Mead and the desert roads, as well as some Mount Charleston roads, can be seen.
Elvis wins the race and the girl.
The final minute of the movie shows Elvis and Ann exiting the Last Frontier's Little Church of the West.
(Note:) In the crowd of well-wishers the Flamingo's publicist Abe Schiller can be seen on the right. Abe was once known by the title 'Mr. Las Vegas' long before Wayne Newton or George Wallace used the label. Abe was also known as 'The Jewish Cowboy' due to the simple fact that he wore very extravagant, jeweled cowboy clothes, designed by Nudie, most everywhere he went.
