Grease is a 1971 musical with music, lyrics, and a book by Jim Jacobs and Warren Casey. Named after the 1950s United States working-class youth subculture known as greasers and set in 1959 at the fictional Rydell High School in Northwest Chicago (based on Taft High School in Chicago, Illinois, and named after rock singer Bobby Rydell), the musical follows ten working-class teenagers as they navigate the complexities of peer pressure, politics, personal core values, and love.
Grease was adapted in 1978 as a feature film, which starred John Travolta (who himself had been in stage productions in a different role) and British-Australian singer and actress Olivia Newton-John, removed the musical's Chicago urban setting, and changed some plot elements, characters, and songs while adding new songs and elaborating on some plot elements only alluded to in the musical.
