Based on the Lynn Riggs' play Green Grow The Lilacs, Oklahoma! was Rodgers & Hammerstein's first collaboration and, in many ways, remains their most innovative. It has set the standard for modern musical theatre and features such classic musical numbers as "Oh, What A Beautiful Mornin'," "People Will Say We're In Love," "The Surrey With The Fringe On Top" and the title song. Set in the territory of Oklahoma at the turn of the century, against the background of the rivalry between cattlemen and farmers, this musical! is the story of the farm girl, Laurey, and the two rivals for her affection: the cowboy, Curly, and the brooding farmhand, Jud.
