Grease is a 1971 musical by Jim Jacobs and Warren Casey with additional songs written by John Farrar. Named for the 1950s United States working-class youth subculture known as greasers, the musical is set in 1959 at fictional Rydell High School (based on Chicago, Illinois' William Howard Taft School) and follows ten working-class teenagers as they navigate the complexities of peer pressure, politics, personal core values, and love.
