South Pacific is a musical composed by Richard Rodgers, with lyrics by Oscar Hammerstein II and book by Hammerstein and Joshua Logan. The work premiered in 1949 on Broadway and was an immediate hit, running for 1,925 performances. The plot of the musical is based on James A. Michener's Pulitzer Prize-winning 1947 book Tales of the South Pacific and combines elements of several of those stories. Rodgers and Hammerstein believed they could write a musical based on Michener's work that would be financially successful and, at the same time, would send a strong progressive message on racism.
The plot centers on an American nurse stationed on a South Pacific island during World War II, who falls in love with a middle-aged expatriate French plantation owner but struggles to accept his mixed-race children. A secondary romance, between a U.S. lieutenant and a young Tonkinese woman, explores his fears of the social consequences should he marry his Asian sweetheart. The issue of racial prejudice is candidly explored throughout the musical, most controversially in the lieutenant's song, "You've Got to Be Carefully Taught". Supporting characters, including a comic petty officer and the Tonkinese girl's mother, help to tie the stories together. Because he lacked military knowledge, Hammerstein had difficulty writing that part of the script; the director of the original production, Logan, assisted him and received credit as co-writer of the book. -Wikipedia
