1 day to go before "Glee" season 4 premieres on ETC and Jack TV. For a teaser, check out Glee cast's full performance video of Carly Rae Jaepsen's hit song "Call Me Maybe."

On the promotional video released by Fox, we find former Audio Adrenaline member Wade “Unique Adams,” played by The Glee Project season 1 finalist Alex Newell, as a new member of New Directions. Perhaps he was convinced by Blaine and Kurt to transfer to McKinley.

“Glee” season 4 stars Matthew Morrison, Jane Lynch, Lea Michele, Cory Monteith, Amber Riley, Chris Colfer, Kevin McHale, Jenna Ushkowitz, Mark Salling, Dianna Agron, Heather Morris, Naya Rivera, Harry Shum Jr. and Darren Criss.

Kate Hudson and Sarah Jessica Parker (“Sex and the City”) will also join the hit TV musical series this season for a multi-arc guest appearance.

“Glee” Season 4 premieres on Sept. 14 at 4 p.m. via satellite with a primetime telecast at 8 p.m. on Jack TV and ETC.
