1978 single by John Travolta and Olivia Newton-John
"Summer Nights" is a popular song from the musical Grease. Written by Jim Jacobs and Warren Casey,[1] its best-known version was recorded by American actor and singer John Travolta and British-Australian singer, songwriter and actress Olivia Newton-John for the 1978 big-screen adaptation of the musical, and released as a single that same year. It was released in August 1978 as the fourth single from the movie's soundtrack album and became a massive hit worldwide during the summer of 1978. Parts of the song were introduced to a new audience when it was re-released in the 1990s as part of a megamix of several songs from the movie version.
