For his last show of 2015, James Corden had a special treat for fans of his Carpool Karaoke segments. While driving around Los Angeles, Corden was in the mood for some Christmas music. After turning on the rado, guests of Carpools past showed up to sing along. Stevie Wonder, Rod Stewart, Justin Bieber and more reprised their roles in the passenger seat to help Corden belt out “Joy to the World.”
It came to no surprise that Carrie Underwood and Jason Derulo can hold a note. Iggy Azalea ad-libbing a line, however, was a highlight considering her aversion to such things.
