"John Wayne Gacy, Jr." by Angie Hart is actually a cover of the song originally written by Sufjan Stevens. The song explores the chilling and disturbing story of John Wayne Gacy Jr., an American serial killer who sexually assaulted and murdered at least 33 young boys and young men between 1972 and 1978.

The lyrics begin by painting a picture of Gacy's troubled childhood. His father was an alcoholic, his mother suffered emotionally, and he had a traumatic accident involving a swingset. Despite these difficult circumstances, Gacy was able to charm his neighbors with his humor and conversation.

The chorus of the song highlights the shock and horror of discovering Gacy's crimes. The phrase "are you one of them?" suggests a sense of disbelief and questioning whether others could be capable of such darkness.

The second verse delves into Gacy's sinister portrayal as a clown. This references his actual persona as "Pogo the Clown" that he used to entertain children at parties and events. The line "on his best behavior, in a dark room on the bed, he kissed them all" describes his predatory behavior and the manipulation he used to gain his victims' trust.

The outro of the song draws a parallel between Gacy and the songwriter herself. It suggests that hiding beneath someone's seemingly good behavior lies the potential for darkness and secrets. It raises the theme of examining one's own actions and questioning the potential for evil within oneself.

Overall, "John Wayne Gacy, Jr." explores the disturbing actions of a notorious serial killer and subtly raises questions about the capacity for evil that may exist within all of us. It serves as a chilling reminder of the darkness that can be hidden in plain sight.
