On the episode, Sabrina and her friends discovered a poster for an old Battle of the Bands competition between Satanic Panic and Fred Heads.
In case the band name sounded familiar, that's because it was referenced on "Riverdale."
Season three, episode four of "Riverdale" showed young Fred Andrews performing with his band, called Fred Heads.
The group was comprised of Fred, Hermione Lodge (née Gomez), Alice Cooper, FP Jones, and Sierra McCoy (née Samuels).
During the episode, they played "Dream Warriors," the theme song from "A Nightmare on Elm Street 3."
