The Colbert Report aired its final episode tonight and it was as funny and over-the-top as everyone expected. But the best part had to be the finale's ending musical number which was downright badass.

Stephen Colbert literally had every single famous person in the world on stage with him for this number. They all sang "We'll Meet Again" and it was beautiful. There were way too many people to name right now, but here's the ones I can remember as I type this out: Alan Alda, Jon Stewart, Willie Nelson, Bryan Cranston, Tom Brokaw, Mandy Patinkin, Neil deGrasse Tyson, Big Bird, Cookie Monster, Michael Stipe, Cindi Lauper, Katie Couric, James Franco, Charlie Rose, Barry Manilow, Jeff Daniels, Patrick Stewart, Dr. Francis Collins, Andy Cohen, Henry Kissinger, Andrew Sullivan, Arianna Huffington, Kareem Abdul Jabbar, Christian Amanpour, Goerge Lucas, J.J. Abrams, Bill Clinton, Keith Olbermann, Jeff Tweedy, Tim Meadows, Mike Huckabee, Mark Cuban, Bob Costas, Ken Burns,Gloria Steinem, Thomas Friedman, Claire McKaskill, David Gregory, Eliot Spitzer, Yo Yo Ma, John Ratzenberger, Samantha Power, Vince Gilligan, Doris Kearns Goodwin, Bill DeBlasio, Randy Newman, Sam Waterston, Toby Keith, Bo Dietl, Cory Booker, Elijah Wood, Pussy Riot, Leslie Stahl, Smaug, Eleanor Holmes Norton, Debra Wilson, Paul Krugman, Jon Batiste, Stone Phillips, Peter Frampton, Alexi Lalas, Chuck Schumer, Chief of Staff of the Army General Ray Odierno, Nate Silver, Bradley Whitford, Jake Tapper, Jeffrey Toobin, Leon Wieseltier, Ric Ocasek, Dean Kamen, Trevor Potter, Jon Alter, Richard Clarke, Norm Ornstein, David Hallberg, Kevin Spacey, Grover Norquist, George Saunders, astronaut Garrett Reisman in ACTUAL SPACE, a group of military servicemen and women in Afghanistan and a WHOLE BUNCH OF OTHERS. Alex Trebek also made an appearance at the very end, but was not part of the musical number.

List as many as you can spot in the comments below; I'll update as I spot more! Also, if I've misidentified anyone or have the wrong name here, let me know.

It was at times funny but mostly, it was a touching, rousing way to say goodbye to one of the most hilarious and unique television personalities in history.
