The first collaboration between composer Richard Rodgers and librettist Oscar Hammerstein II remains, in many ways, their most innovative. It was one of the first Broadway musicals to fully integrate song-and-dance numbers — including “Oh, What a Beautiful Mornin’,” “People Will Say We’re In Love” and the rip-roaring “Oklahoma!” — into the story. Set in Indian Territory just after the turn of the 20th century, the high-spirited rivalry between local farmers and cowboys provides a colorful background against which Curly (Sam Briggs), a handsome cowboy, tries to win the heart of Laurey (Ruby Shadley), a winsome farm girl. With these two headstrong romantics holding the reins, their courtship is as bumpy as a surrey ride down a country road, but the appeal of a brand-new life together in a brand-new state proves irresistible. Oklahoma, OK!
