This is a re-recorded version of the song ONJ sang in the hit movies Grease (1978). As the record label RSO were in possession of the soundtrack rights to that movie and Paramount Pictures were the distributors of the movie, ONJ had to re-record the song and make a new video for inclusion on her greatest hits album in 1982 (published by EMI records) as neither RSO or Paramount would let her use the original recording or footage.
