The early 1950s saw a rising popularity in the rock n’ roll music style, with popular artists such as Elvis Presley and Buddy Holly. This era of music influenced many, as well as the main influence of the popular musical Grease. Written by Jim Jacobs and Warren Casey, this 1971 musical took form with many rock-influenced scores, as well as doo wop. Those scores reflected the culture of the 1950s adolescent teenage society.

He is best known for writing the book, lyrics and music, with Warren Casey for the stage and film musical Grease. Warren Casey, April 20, 1935- November 8,
