Sweet a cappella cover of Fun's hit song "We Are Young"

(CBS News) In the past month we've had a hilarious parody coverand guitar cover of the hit song "We Are Young" by Fun (both with twists worth seeing). But we'd been missing something that I couldn't quite put my finger on until just this moment: a cappella!

Not too shabby at all, right?  The sweet music video was done by a cappella group Pentatonix, who you may previously know from their amazing vocal stylings on NBC's "The Sing Off".  We'd like to go ahead and give Pentatonix a nice, big triple-rainbow salute for their excellent cover of the hit song!
