Nick Jonas recently did one of James Corden’s “Carpool Karaoke” segments with Demi Lovato, and in a new interview, he dropped some inside information.
For instance, they can’t run the air conditioning because it’ll ruin the sound, so the car gets extremely hot. He said, “For some reason, I decided to wear this jacket and I’m just sweating in the car and Demi kept looking back at me and was like ‘What’s the matter with you?'”
Nick also said he wanted to make sure he knew the words to the songs, and for him, he definitely wanted to know Demi’s, but he stopped short of saying they get tipped off about what songs will be played. That’s all he revealed, but it inspired us to do some more digging.
So here are five other interesting facts about “Carpool Karaoke”:
1. There’s no green screen. The car is real, and it’s not on a trailer. James is really driving, although he’s not doing 70 mph down the interstate or anything. The show’s producer says they’re easy routes. The streets aren’t blocked off and so there are other cars, but he’s never going more than 20 miles-per-hour.
2. James’ car is part of a convoy. The show has two cars ahead of him, and three behind him. And they don’t let any other cars around him for safety reasons.
3. As Nick said, they record the sound directly from the car, and there are tiny cameras the size of your knuckle stuck on the windshield. They’re not big enough to distract James’ view.
4. They film for about an hour, and then the editor trims it down. Usually, they’re left with about 15 minutes of good stuff, but when Adele did it, she was having so much fun that she stayed in the car for more than two hours, and they ended up with 54 minutes of good footage.
The final cut of her episode is 15 minutes long, and it’s a classic, with 110 million views, a record for a late night video.
A producer says they probably won’t release any of the outtakes.
5. The idea for Carpool Karaoke came from a skit that James did for the U.K.’s Comic Relief charity event in 2011. It featured him singing in the car with George Michael.
