'Grease' is the title song for the musical motion picture Grease, which was based on the stage play of the same name. The song was sung by Frankie Valli and was featured twice on the film's soundtrack, as the first track and reprised as the final track. It became a No. 1 single in the United States in 1978 and also reached No. 40 on the R&B charts in the same year. The song was written by Barry Gibb of the Bee Gees. The Bee Gees would later perform the song in concert, as captured on their live offering One Night Only.
