This week’s episode of HBO’s True Blood covered a wide array of music, including classic blues from John Lee Hooker, early rock and roll from Carl Perkins and…Katy Perry?

True Blood showed their pop bonafides in a scene where vampires Russell Edgington (Denis O’Hare) and Steve Newlin (Michael McMillian) went to a fraternity party where they drained the attendees. As the two slow danced together while surrounded by bloody bodies, Katy Perry’s upbeat “Teenage Dream” played in the background. The lyrics “We can dance until we die/You and I, we’ll be young together,” are apt, provided that neither character meets the “true death.”

Music supervisor Gary Calamar told CBS Local that the True Blood team had a good time debating what song would work best.

“We wanted a big, recognizable pop song that would show the twisted romance of Russell and Newlin… and would also work ironically against the drained college students. We tried Rihanna, Far East Movement, Maroon 5… but ‘Teenage Dream’ worked the best on all levels.”

“Plus,” he confesses, “Katy Perry is one of my guilty pleasures.” And echoing what is on the minds of many fans of the pop singer, or those who frequent gossip websites, “[I’m] hoping she moves past the John Mayer fling quickly.”

The episode, titled “Gone, Gone, Gone,” led fans to expect to hear some variation on the Everly Brothers song of the same name, which was recently covered by Robert Plant and Alison Krauss on their Grammy-winning Raising Sand album. Instead, True Blood used the Carl Perkins song “Gone, Gone, Gone” beneath an emotional scene where Hoyt Fortenberry (Jim Parrack) asks his ex-girlfriend, vampire Jessica Hamby (Deborah Ann Woll) to wipe his memory of her after she cheated on him with his best friend. In the background, “Gone, Gone, Gone” played, with its lyrics, “Well that must be my girl, yours don’t look like that.”

True Blood’s episode titles are generally inspired by songs that play during the end credits. However, instead of “Gone, Gone, Gone” the episode closed with John Lee Hooker’s “You Know, I Know.” The lyrics: “You know, I know, we’re gonna get together one day,” leading fans to wonder which characters inspired the song choice.

Calamar noted that both song choices came from the episode’s writer, Alex Woo. “I had suggested that we do a new cover on ‘Gone, Gone, Gone’ but Alex loves the Carl Perkins version on Sun Records, so we went with that.”
