Grease is a 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[1] (based on Taft High School in Chicago, Illinois,[2] and named after rock singer Bobby Rydell[3]), the musical follows ten working-class teenagers as they navigate the complexities of peer pressure, politics, personal core values, and love.[3]
