Oklahoma! is the first musical written by the team of composer Richard Rodgers and librettist Oscar Hammerstein II. The musical is based on Lynn Riggs' 1931 play, Green Grow the Lilacs. Set in Oklahoma Territory outside the town of Claremore in 1906, it tells the story of cowboy Curly McLain and his romance with farm girl Laurey Williams. A secondary romance concerns cowboy Will Parker and his flirtatious fiancée, Ado Annie.
The original Broadway production opened on March 31, 1943. It was a box-office smash and ran for an unprecedented 2,212 performances, later enjoying award-winning revivals, national tours, foreign productions and an Academy Award-winning 1955 film adaptation. It has long been a popular choice for school and community productions. Rodgers and Hammerstein won a special Pulitzer Prize for Oklahoma! in 1944.
