The song sketch first hit the airwaves back in 2000 as part of Season 26, with Horatio Sanz on guitar, Jimmy Fallon on keyboard, Chris Kattan on… holding the keyboard, and Tracy Morgan doing a little dance.
For the December 18 episode of The Tonight Show Starring Jimmy Fallon, Fallon brought a bunch of his old Saturday Night Live pals together (along with Ariana Grande) for a performance of their classic SNL song, “I Wish It Was Christmas Today.”
