“We Are The Champions” A Capella From Jimmy Fallon [VIDEO]

I love anything a capella, but leave it to Jimmy Fallon to get this many A-listers together to sing Queen! In honor of the Super Bowl, Jimmy and the Roots join Carrie Underwood, Sam Smith, Ariana Grande, Blake Shelton, Usher, Meghan Trainor, One Direction, and Christina Aguilera for an a cappella version of "We Are The Champions."
