The soundtrack includes two versions — one by the Bee Gees and the other by Tavares. Both versions are featured in the film as well. The song has been recorded and performed by various artists but in different forms. The Bee Gees did not release this song as a single (though in Italy it peaked at #4 in 1978), yet it has remained a staple on radio and one of their best known songs. An abridged live version of the song performed by the Bee Gees in 1997 is available on both the DVD and CD versions of One Night Only.
The song has also been included on Bee Gees compilations such as Tales from the Brothers Gibb and Their Greatest Hits: The Record. The very first British pressings of Their Greatest Hits: The Record featured the song with a mastering fault, with the audio noticeably dipping to the right briefly during the first verse. This was corrected after several thousand copies had been distributed.
The video is taken from Saturday Night Fever. It shows John Travolta dancing in a club.
