One of the longest-running shows in Broadway history, this nostalgia-fueled musical is set in the 1950s at Rydell High School, where bad-boy Danny Zuko and sweet-natured Sandy Olsson navigate love, friendship, and the pressure to fit in. With an infectiously fun score featuring "Summer Nights," "Greased Lightnin'," and "Hopelessly Devoted to You," Grease has become a beloved cultural touchstone with multiple Broadway revivals, a blockbuster 1978 film, and productions around the world.
