Grease

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 greasers. The musical, set in 1959 at fictional Rydell High School (based on Chicago, Illinois (William Howard Taft School), follows ten working-class teenagers as they navigate the complexities of love. 

The score attempts to recreate the sounds of early 1950's 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. (Taken from Wikipedia)

I watched Grease last week as a requirement for my English class since we had to decide for our play proposal and I thoroughly enjoyed this classic movie.
