Jim’s musical journey began in earnest when he moved to New York City, after graduating from Northwestern University, where he studied theater and acting.

The Genesis of Grease

In the bustling city of New York, Jim Jacobs found himself struggling to find acting work. However, it was during this period that he started writing sketches and scenes, which he performed at small theaters. This was where he met Warren Casey, a fellow playwright. The duo bonded over their shared love for early rock and roll music and 1950s nostalgia, and thus, the idea for a musical set in this era was born. After several years of work, their musical “Grease” premiered in 1971 at the Kingston Mines Theater in Chicago.

“Grease” was an instant hit, leading to its transfer to Broadway in 1972, where it ran for almost a decade.

The 1978 film adaptation, starring John Travolta and Olivia Newton-John, further expanded the reach of “Grease”, turning it into a global phenomenon.
