Too often, once these rides — with all their on-point harmonizing and covering — end, Corden’s guests quip that he’d make a good addition to their next tour. He agrees. But he never gets called. He’s starting to feel like that friend you’ve been planning the same Sunday brunch with for nine months now. That’s why he turns the above Demi-Nick carpool into more of an audition. And as you’ll see, once Corden, Jonas, and Lovato get all the talk about purity rings, rabid fandoms, and “Cake by the Ocean” out of the way, J makes a strong case for JND with a “Confident” sidewalk performance. Maybe next year.
