Watch The Colbert Report’s HUGE celebrity sing-along for the final episode of the show.

I can’t believe it’s over! For the very last episode of ‘The Colbert Report’ ever, Stephen Colbert threw a massive celebrity sing-along that was so mind-blowingly star studded you might have to watch it a few times to catch all of the special guests. Every celebrity, writer, musician, politician, host and muppet who loves Stephen stopped by his final taping to give him a proper musical send off.

Get ready for a celebrity lightening round because Jon Stewart, Willie Nelson, Katie Couric, Neil DeGrasse Tyson, Vince Gilligan, JJ Abrams, Big Bird, Jeff Bridges, Sam Waterston, Gloria Steinem, James Franco, Cindy Lauper, Michael Stipe, Kareem Abdul Jabar, Barry Manilow, Sir Patrick Stewart, Andy Cohen, Christiane Amanpour, Ariana Huffington, Cory Booker, Tim Meadows, Cookie Monster, Howard Stern, Bryan Cranston, Elijah Wood, Mark Cuban, Pussy Riot, Henry Kissinger, and Smaug are all gathering ’round the piano to sing ‘We’ll Meet Again’ and bid a fond farewell to The Colbert Report as Stephen moves on to ‘Late Show with Stephen Colbert‘, taking Letterman’s place.
