TVLine Items: Glee Catches Saturday Night Fever, Secret Circle Conjures Up Cassie's Dad and More!

Glee will be Stayin’ Alive this April with a Saturday Night Fever-themed episode.

“We’ve never done disco on the show, but I’m interested in the genius of The Bee Gees,” executive producer Ryan Murphy told TV Guide Magazine. This installment of the hit Fox musical will honor the soundtrack to the 1977 John Travolta flick — and may even include a cameo from the movie star himself. Murphy explains that Travolta and Cory Monteith are real-life pals, “So maybe we’ll have them dance in a Finn dream sequence.”

Hmm, considering this week’s Glee includes a riff on Grease, can we expect a musical homage to Blow Out anytime soon?
