A new behind-the-scenes video for the final season of Fox's Glee has been released, with new footage detailing the "homecoming" episode.

Most of the show's graduated kids will be back in the second episode of Glee's final season as a homecoming will be arranged. The episode features the kids singing Take On Me by a-ha, which is featured in a new behind-the-scenes clip from Entertainment Tonight.

Jane Lynch (who plays Sue Sylvester) speaks of the episode in the video:

"It's the beginning of the end we are in season six and all of the kids are back at McKinley so we've got the original group of people from the first season," Lynch says. "Mark Salling is back today as Puck, Quinn Fabray [aka] Dianna Agron is back. Oh! Naya [Rivera] and Heather [Morris] are back so we've got Brittana."

With Sue abolishing all arts programs from McKinley High, Rachel (Lea Michele) and Kurt (Chris Colfer) take it upon themselves to start up the new New Directions.

"They have exactly zero members of the glee cub when we meet them in the first episode so they're on the warpath to recruit students and it's not easy," Lynch explains.

The Take On Me performance appears to be very elaborate with some special effects even being integrated, a rarity on Glee.

Glee returns for its sixth and final season on Friday, Jan. 9 at 8 p.m. ET/PT on Fox.
