This song was written and produced by Barry Gibb of The Bee Gees specifically for the movie. His music helped make Saturday Night Fever
a huge hit two years earlier. That film was produced by Robert Stigwood, who was a partner in the Grease
movie and got Gibb on board for the title song.
For this project, Stigwood was interested in Gibb's pen, but not his voice, since The Bee Gees sound ingrained with Saturday Night Fever
and he wanted Grease
to have its own identity. Frankie Valli
, who could sing in a similar high vocal range to Gibb, was asked to record it. Thanks to his many previous hits, Valli provided a familiar sound, but one that was not saturated on Pop radio, as he hadn't had a hit for a while. Gibb did sing backup on the track.
