"Chariots of Fire" is an instrumental theme written and recorded by Vangelis for the soundtrack of the 1981 film of the same name. It has been covered by numerous performers and used for various television programs and sporting events.
On the film's soundtrack album, the piece is called "Titles" because of its use in the movie's opening titles sequence, but it widely became known as "Chariots of Fire".
When the single debuted at #94 on the Billboard Hot 100 during the week ending 12 December 1981, it was known as "Titles". Seven weeks later, when it moved to #68 on the Hot 100 chart dated 30 January 1982, the single was listed as "Chariots of Fire"; it stayed with that name for the remainder of its chart run. The new name made it easier for both listeners and radio DJs to identify the piece.
According to AllMusic, the track was listed as "Chariots of Fire - Titles" on the U.S. Billboard Hot 100 chart, and simply as "Chariots of Fire" on the Adult Contemporary chart. A 1989 CD single release also gave the name of the piece as "Chariots of Fire".
