In this musical comedy sketch, Michael Bublé (playing himself) is in a recording studio working on his Christmas album with various music superstars. Each celebrity guest - played by SNL cast members doing spot-on impressions - performs classic Christmas songs in their signature style, which increasingly frustrates the earnest crooner. Jimmy Fallon appears as multiple celebrities including Sting (singing "fa la la" to the tune of "Don't Stand So Close To Me"), Russell Brand, and Justin Bieber. Kristen Wiig plays Taylor Swift with her characteristic surprised expressions, Nasim Pedrad brings M.I.A.'s aggressive style to "Up on the Rooftop" with gunshot sounds, Fred Armisen channels Thom Yorke's moody Radiohead persona, Jay Pharoah delivers an over-the-top Kanye West bragging about being better than baby Jesus, and Taran Killam does Scotty McCreery. The sketch culminates with a Christmas tree representing Lady Gaga. The humor derives from the contrast between Bublé's traditional Christmas style and each artist's eccentric personality.
