'Riverdale': Check Out the Vixens Performing "Jailhouse Rock"

Never afraid of going full-on campy for a good story, tomorrow's episode of Riverdale will feature a group of high school cheerleaders performing "Jailhouse Rock" in order to entertain a group of inmates at a juvenile detention facility.

...Accompanied, yes, by a boombox with a built-in tape deck.

You can check out the video above, which Warner Bros. Television has posted to YouTube ahead of the episode.

Veronica, Josie, and Cheryl lead the River Vixens in a performance of "Jailhouse Rock" for Archie and his fellow inmates in "Chapter Thirty-Seven: Fortune and Men's Eyes."

The episode is named after a play (and later film) that explores themes of prison violence, gangs, and homosexuality. The episode is likely to deal with at least a few of those, given that it will be depicting the first part of Archie's two-year stretch in juvie.

Their choreographed routine takes place during a clean, fair football game designed by Archie to bring together the Ghoulies and the Serpents. Both Warden Norton and Veronica's father, Hiram Lodge, are less-than-pleased by Veronica's attempt to bolster Archie's spirits, leaving her to find a new way to visit Archie at the Juvenile Detention Center.

"Jailhouse Rock" was written by legendary songwriting duo Jerry Leiber and Mike Stoller for three-time Grammy winner and Grammy Lifetime Achievement recipient Elvis Presley, and they later wrote the movie score for Presley's film by the same name. The song was a number one hit in the United States for seven weeks in 1957, and it was named one of The Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. Songwriter Hall of Fame inductees Leiber and Stoller also penned numerous other songs performed by Presley. The song has gone on to feature in a number of film and television projects without Presley's direct involvement, most memorably in the final scene of the classic comedy The Blues Brothers.

Riverdale stars KJ Apa, Lili Reinhart, Camila Mendes, Cole Sprouse, Luke Perry, Mädchen Amick, Marisol Nichols, Madelaine Petsch, Ashleigh Murray, Casey Cott, Mark Consuelos, and Skeet Ulrich.
