Several years later, Hall read an interview with serial killer David Berkowitz, in which he claimed that "Rich Girl" had motivated him to commit the notorious "Son of Sam" murders (although the song was not released until after the Son of Sam murders had already begun, casting doubts on that suggestion). Hall & Oates later reflected this disturbing fact in the lyrics of the song "Diddy Doo Wop (I Hear the Voices)" on the album Voices.
