Viva Las Vegas is an EP by American singer Elvis Presley, containing four songs from the 1964 motion picture, Viva Las Vegas. It was released by RCA Victor in May 1964 to coincide with the film's premiere. The soundtrack EP made the Billboard Hot 100 at No. 92, the lowest-charting release of Presley's career to this point. RCA had not released a Presley EP single in two years; given the format's decreasing popularity in the United States and the disappointing chart performance of Viva Las Vegas, the company would only issue two more for the remainder of Presley's career.

Kissin' Cousins is the eighth soundtrack album by American singer and musician Elvis Presley, released by RCA Victor in mono and stereo, LPM/LSP 2894, in April 1964. It is the soundtrack to the 1964 film of the same name starring Presley. Recording sessions took place at RCA Studio B in Nashville, Tennessee, on May 26 and 27, and September 29 and 30, 1963. It peaked at number six on the Billboard Top LPs chart. The album was certified Gold on March 27, 1992 by the Recording Industry Association of America.
