Grease is a 1971 musical by Jim Jacobs and Warren Casey. The musical is named for the 1950s United States working-class youth subculture known as the greasers. The musical, set in 1959 at fictional Rydell High School (loosely based on William Howard Taft School), follows ten working-class teenagers as they navigate the complexities of love, cars, and drive-ins. The score attempts to recreate the sounds of early rock and roll. In its record-breaking original Broadway production, Grease was a raunchy, raw, aggressive, vulgar show. Subsequent productions sanitized it and tamed it down. The show tackles such social issues as teenage pregnancy and gang violence; its themes include love, friendship, teenage rebellion, sexual exploration during adolescence, and, to some extent, class consciousness/class conflict. Grease was first performed in 1971 in the original Kingston Mines Theatre in Chicago, located in an old trolley barn (now the site of a hospital parking garage).
