This plays at the finale of the movie Grease
as John Travolta (Danny) and Olivia Newton-John (Sandy) overcome the social constraints of high school and declare their lust for each other. Like the title track
, it was not in the original stage musical of Grease
, but was written specifically for the movie. Also like the title track, it was a #1 hit in America, reaching the top spot on June 10, 1978. This is very impressive considering the movie was not released until June 16, making the song a hit on its own merits and providing tremendous anticipation for the film. The title track rode the movie's momentum to #1 on August 26, and stayed there for two weeks.
