Over the last few months, James Corden has taken several singers in his car for Carpool Karaoke. What we didn’t know is that he was secretly recording a song with all of them and yesterday he debuted their version of Joy to the World on The Late Late Show. One Direction, Stevie Wonder, Iggy Azalea, Rod Stewart, Carrie Underwood, Jason Derulo, Justin Bieber and the CBS late night host all did such a joyful version of holiday tune that it lived up to its name.
I dare you to listen to it only once. I am already up to my 15th time and counting.
