On The Dark Side by John Cafferty & the Beaver Brown Band. This was written for Eddie and the Cruisers, a 1983 movie about a New Jersey bar band. In the film, the song becomes the band's big hit and leads to a second album and a conflict with their record company. Kenny Vance was the music supervisor on Eddie and the Cruisers.
One of the most famous albums of Pink Floyd is 'The Dark Side of the Moon'. Besides the title of the album, this phrase also appears in the lyrics of the last song of the album, Eclipse: And if the cloud bursts, thunder in your ear. You shout and no one seems to hear. And if the band you're in starts playing different tunes. I'll see you on the dark side of the moon.
