Episode 7 kicks off like no other “Peacemaker” episode we’ve seen so far. Flashing back to the titular character’s childhood, we see a young Christopher Smith (aka Peacemaker) and his brother, Keith, browsing through a vinyl collection, including records from Motley Crue and Kiss. As the two brothers simulate drum solos with pencils, they listen to “Home Sweet Home” by Motley Crue. Given his piano rendition of the song in Episode 6, it’s very clear that this particular song means a lot to Peacemaker.
Flashing back to the present day, Peacemaker and Vigilante (Freddie Stroma) later join John Economos (Steve Agee) in a car in the team’s van. Peacemaker and Vigilante dance to “In My Dreams” by Wig Wam. As our heroes battle the forces of the Butterflies and the White Dragon, it’s repeatedly shown that there’s no bad time to switch. After an attack by the white supremacist band, Vigilante swoons to the ironically chosen sounds of Kix’s “Don’t Close Your Eyes.” Later, when Peacemaker and Economos locate Vigilante’s vehicle, they do their best to escape certain death as Hardline’s 1992 song “Hot Cherie” plays on the radio (via Discogs).
Later, as Harcourt briefs the team and the butterflies prepare to move the cow, we hear “By The Grace of God,” a song by a Swedish rock band called The Hellacopters (via Discogs). The penultimate episode of “Peacemaker” enters the closing credits to the sound of “Set The Night on Fire,” a song by Pretty Boy Floyd. This is the band’s second use of a song, following the appearance of “I Wanna Be With You” in episode 4. While the band’s exact plan for the butterfly cow is not clear at this point, maybe the fiery credits song could be a clue?
