The night wouldn't be the same without Tonight Show house band The Roots, of course — same goes for Justin Timberlake, who duets on Holiday Seasoning track "You'll Be There."

"It's a ukulele type of bromance song. I'm calling him during the holidays, and he won't pick up the phone — but listen to the end of the song, and it gets funny," Fallon explained during a Tonight Show track listing reveal.

Check out the full list of performers and celebrities who'll appear on Jimmy Fallon's Holiday Seasoning Spectacular special below:

  • The Roots 
  • Dolly Parton
  • Justin Timberlake
  • J.B. Smoove
  • Cara Delevingne
  • Jonas Brothers
  • "Weird Al" Yankovic
  • LL Cool J
  • Mariah Carey

Yuletide queen Mariah Carey is one festive guest — and so are The Rockettes, the high-kicking dancers who are a New York City institution.

Like Timberlake, Cara Delevigne, Jonas Brothers, "Weird Al" Yankovic, and Dolly Parton also guest on Holiday Seasoning. 

As for Yankovic's song with Fallon and The Roots, "New Year’s Eve Polka (5-4-3-2-1)," Fallon describes it as the upbeat New Year's anthem we deserve. 

"There's no fun New Year's Eve songs. They're all sad. There's 'Auld Lang Syne.' I don't know what it means, but it's sad," Fallon said on The Tonight Show. "That's probably about it. But this is a peppy one. I figured, what genre just makes you happy no matter what it is? And I thought, polka."

Fallon describes "Holiday" featuring Jonas Brothers as "a roller-disco jam." And the hilarious "Hallmark Movie" with Delevigne is a rom-com gone hilariously, darkly wrong.
