Sunday night, in honor of the Super Bowl, Jimmy Fallon and the Roots joined Carrie Underwood, Sam Smith, Ariana Grande, Blake Shelton, Usher, Meghan Trainor, One Direction, and Christina Aguilera for an a cappella version of Queen's "We Are The Champions."

The performance starts out with Fallon singing solo, and as it picks up steam, more artists join into the mix, while The Roots provide the a capella drum and instrument noises.

Underwood joins in first, followed by the ever-lovely Smith, Grande and the rest.

In the end, it ends up looking like a star-studded, bigger version of the opening credits to "The Brady Bunch."
