Can you believe Glee is airing its Season 4 finale on Thursday? It seems just like yesterday when Rachel, Finn, Mercedes, Quinn, Mike, Puck and Santana graduated from McKinley High. Don’t expect another commencement ceremony on the finale this season. Ryan Murphy is splitting up the school year between Season 4 and Season 5. Instead, here’s what to expect on Thursday.

Kurt (Chris Colfer) and Blaine (Darren Criss) might or might not get engaged. An older lesbian couple (Kurt and Blaine in 20 years *wink*) played by TV vets Meredith Baxter and Patty Duke will undoubtedly play a factor in that. With regards to New Directions, they compete at Regionals against a formidable team headlined by Frida Romero portrayed by American Idol Season 11 runner-up Jessica Sanchez.

In the meantime, Rachel heads to her Funny Girl callback. Will she choke or will she be Broadway bound for Glee Season 5? More importantly, what is she singing? Find out below. A few of the artists covered on the finale include Icona Pop, The Script, Celine Dion, Little Mix, DJ Zedd and an original track. Check them all out below.

“Wings” by Little Mix

“Clarity” by DJ Zedd

“I Love It” by Icona Pop

“Hall of Fame” by The Script

“To Love You More” by Celine Dion

“All or Nothing” Original Song
