After the New England Patriots narrowly came out on top at Super Bowl XLIX, The Tonight Show serenaded the Pats and their rival Seattle Seahawks with a 1970s classic.
To keep the festive atmosphere going after Sunday's big game finished, Jimmy Fallon called on a number of his A-list friends to perform an a cappella rendition of Queen's "We Are the Champions."

Case in point: Monday, when the chameleonic host and house band The Roots (the "hardest-working band in late night," as Fallon calls them) took over for U2, who were forced to cancel their appearance after Bono took a spill on his bicycle. (An incident that followed his plane's hatch opening mid-flight – it's been a rough week.)

You've seen "Let It Go" performed by a 9-year-old. You've seen it performed in Times Square. You've even seen it performed by Adele Dazim. But you've never seen it like this.

Possibly more than any other show, Fallon's Late Night understood the science of making comedy bits go viral. The formula was easy to explain, but hard to master: Take a celebrity, give him or her a trending topic and find a cutesy, nostalgic spin, then hopefully watch the views roll in.

Mariah Carey's "All I Want for Christmas Is You," can be heard everywhere during the holiday season, but you've never seen it performed like this before!
Backstage before Tuesday night's taping of Late Night with Jimmy Fallon, Carey, her host and his backing band, the Roots, put a quirky spin on the pop star's holiday hit by performing the song using classroom instruments.
Adding to the adorable factor: a quartet of kids who pop up occasionally to sing backup.
