I'm sure you've heard the story about how Michael Sembello originally wrote "Maniac", intent on having it used in a horror movie (naturally). However, it wound up instead on the soundtrack to "Flashdance", and became a #1 hit.
Sembello appeared on American Bandstand to perform "Maniac". Not sure if the follow-up single, "Automatic Man", was used on the same appearance. Anyway, the lyrics appear on the screen in English & Spanish.
