In honor of Super Bowl 2015, Jimmy Fallon 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.”
The bit aired on a special edition of the Tonight Show starring Jimmy Fallon last night, after the Super Bowl and The Blacklist on NBC.
