Grease is a 1971 musical by Jim Jacobs and Warren Casey.

The musical, set in 1959 at fictional Rydell High School, follows ten working-class teenagers as they navigate the complexities of teen relationships, cars, and drive-ins. The score attempts to recreate the sounds of early rock and roll. Grease was first performed in 1971 in the original Kingston Mines Theatre in Chicago, located in an old trolley barn. From there, it has been successful on both stage and screen. At the time that it closed in 1980, Grease‘s 3,388-performance run was the longest yet in Broadway history. It went on to become a West End hit, a hugely successful film, two popular Broadway revivals in 1994 and 2007, and a staple of regional theatre, community theatre, and high school and middle school drama groups. It remains Broadway’s fourteenth longest-running show.
