Watching this made me wayyyyy too happy....thank you Jimmy Fallon.
For The Tonight Show, he had a bunch of artists/celebs from all different backgrounds sing along to Kelly Clarkson's "Since You've Been Gone" - while not being able to hear themselves.
Nice (and kind of unexpected) to see Mumford & Sons get in on the fun, along with John Oliver, The Roots, and the oh-so off key but oh-so entertaining Shaq. The result is 2 minutes of gold. Press play and enjoy, below.
