Watch Neil Diamond, James Corden's Raunchy Christmas Duet

Singer, 'Late Late Show' host recount office holiday party rager to tune of "Sweet Caroline"

Neil Diamond and James Corden delivered a raunchy Christmas duet about an office holiday party rager to the tune of "Sweet Caroline."

Neil Diamond and James Corden sang a dirty version of "Sweet Caroline," about an outrageous office holiday party on The Late Late Show Wednesday. 

"Sweet Christmastime" found Diamond and Corden trading lyrics about an awkward holiday gathering that descends into sloppy drunkenness after shots are thrown back and the eggnog gets spiked: "Fran touching Stan/ Sexting Val/ Kissing Steve/ Kissing Stu," the pair sing in the hilarious build to the chorus – during which the "So good" refrain was replaced by "So drunk!"

Things get even freakier in verse two when the make out sessions turn into a full-on office orgy, leading Corden and Diamond to tweak the chorus one more time: "Sweet Christmastime (Bah bah bah)/ Our whole office just had sex (Had sex, oh god, so weird!)"

Diamond also stuck around to perform some traditional holiday songs, delivering a Christmas medley from his new album, Acoustic Christmas. The tune includes "Santa Claus is Coming (It's Almost Day)" – a Lead Belly song notably recorded by the Weavers – and "We Wish You a Merry Christmas."
