After taking on Gotye's current hit "Somebody That I Used To Know" in its spring premiere this week, "Glee" (Tuesdays at 8 p.m. ET on Fox) is kicking it old school next week.

"Saturday Night Glee-ver," the April 17 episode of "Glee," pays tribute to the classic '70s film "Saturday Night Fever" and its music by The Bee Gees. "Disco, John Travolta, lots of glitter, rollerskating," Jenna Ushkowitz, who plays Tina, says of the episode in a new behind-the-scenes video below.

Mercedes (Amber Riley) sings The Bee Gees' "Disco Inferno" and "she just killed it," Jane Lynch, who plays Sue Sylvester, says of Riley in the new sneak peek.

The upcoming episode also marks the return of Jesse St. James (Jonathan Groff) and the long-awaited introduction of "The Glee Project" finalist Alex Newell's character, Wade.
