Usually, the premise of James Corden’s “Carpool Karaoke” segments is that he needs help with his drive to work, so he recruits a musical guest to give him the assist he’s looking for. He does things differently on the latest installment, though. This time, he’s trying to catch a plane back to Los Angeles, and when his flight gets canceled. So, he reaches out to Kanye West and gets on a plane with him and his Sunday Service choir for the inaugural edition of “Airpool Karaoke.”
