Grease opened in Chicago in 1971 and, on the back of jitterbugging classics like “Summer Nights”, “Greased Lightnin’” and “We Go Together”, proved a touring hit.

The film was released in 1978, starring John Travolta, Olivia Newton-John and Stockard Channing. With songs like "Summer Nights," "Grease Lightning" and others, the movie became a cultural phenomenon.
