On June 16, 1978, forty years ago, an abiding piece of popular culture roared onto screens with the flare of a hot rod: the film version of Grease premiered. Starring heartthrobs Olivia Newton-John and John Travolta as all-American teens in the 1950s, the film broke records and became a cultural touchstone. But it was already a huge hit before the film, as a Broadway musical that had been running for the previous six years.
The huge success belies its low-key origins as the first play written by the duo of Jim Jacobs and Warren Casey. Jacobs had been a student at Chicago's Taft High School during the '50s, while Casey had been a teacher in New York, and the two wrote a somewhat gritty play, as well as a few rock-n-roll songs, about high school kids of the era. The show premiered in 1971 at Chicago's Kingston Mines Theater Company, and within a year had been noticed by producers who wanted to bring it to New York's Off-Broadway. But first they asked Jacobs and Casey to tame the show down and add more songs, turning it into "a fully exploited rock-n-roll musical," as Jacobs told WTTW's John Callaway in 1978, days before the film was released.
