"On the Dark Side" is a song by fictional American rock band Eddie and the Cruisers, released as a tie-in to the 1983 film of the same name.
When initially released in September 1983, the song peaked at No.
When the film was released to home video and pay cable outlets in early 1984, the film as well as the song received renewed interest and the single was relaunched that August.
1 on the Billboard Rock Tracks chart, displacing The Fixx.
John Cafferty & The Beaver Brown Band served as the real-life, officially uncredited stand-ins for the fictional Cruisers on the recording (as they did for the rest of the soundtrack album); only one member of the band, saxophonist Michael Antunes, appeared in the film, and none of the other actors playing Eddie and the Cruisers were musicians.
