For Jimmy Fallon's last waltz on "Late Night" before transitioning to "The Tonight Show," he was joined by some very special guests.

The Muppets dropped by to join Fallon in a sweet, sincere rendering of The Band's seminal 1968 song "The Weight."

Fallon plays drums and sings (Levon Helm-style), while Kermit the Frog, Miss Piggy, Fozzie, Scooter and the rest of the gang take turns signing; Animal screams.  

It's all reminiscent of Martin Scorsese's iconic concert doc "The Last Waltz," but minus Bob Dylan and a coked-out Neil Young. 

The video ends with Fallon leaving the party for another one, just down the hall at "The Tonight Show."
