The Original Soundtrack to the film South Pacific was released by RCA Victor in 1958. The film was based on the 1949 musical South Pacific by Rodgers and Hammerstein. The composers had much say in this recording, with many of the songs performed by accomplished singers rather than the actors in the film. Mitzi Gaynor and Ray Walston were the only two leading performers who did their own singing in the film. The roles of Emile DeBecque, Bloody Mary and Joe Cable were sung by Giorgio Tozzi, Muriel Smith and Bill Lee, respectively. No. 1 on the Billboard 200 for 1 week, from the issue of November 17, 1958.
