The highly-anticipated final sixth season of "Glee" is almost upon us, and Gleeks across the nation are feeling "Glee" fever.

To keep fans reeling for more details and gossip, there have been episode sneak peeks released to whet fans' appetites as part of the build-up.

The "Glee" crew has been spotted by ETonline, who offered up an exclusive first look at the high-energy performance of The A-ha's "Take on Me." Now, it has a bit more of the scoop to share.

"Glee" favorite Jane Lynch (who plays the sinister Sue Sylvester) dished on some of the juicy details.

"In 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 said. "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 the New Directions back, Lynch highlighted the biggest issue facing the "Glee" club alums in this final season.

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

Lynch also shared her enthusiasm with her fans via Twitter: "This has been a blast. Watch Glee FRIDAY for season 6. Photo by @chriscolfer" - Tweeted by Jane (@janemarielynch)
