It's a well-known fact that karaoke is infinitely more fun when you're in a car with James Corden, and no one knows this better than Chris Martin.
The Coldplay singer literally looks like he's about to explode with happiness throughout the epic 15-minute video, which alternates between singing, Martin doing (impressively accurate) celebrity impressions, and talk about the upcoming Super Bowl (Martin has no idea about the rules of American football, by the way.)
There's also a very entertaining pitstop to pick up some lemonade, which makes Martin so gleeful he inexplicably squeals: "I want to punch an elephant!"
