Before they made it big thanks to Stranger Things, Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin, and Noah Schnapp were actually part of a Motown cover band called ‘The Upside Downs" and their frontman was none other than jack-of-all-trades, James Corden.
Okay, so they weren't really. But with season 2 firmly in the books, the boys had a bit of downtime and decided to reunite "the band" for one more show on Corden’s The Late Late Show. As extra as James Corden is, he produced a mockumentary covering the quintet, their beginnings and rise to fame.
Check out the hilarious video above and let Corden, Mike, Will, Lucas and Dustin serenade you with their sweet, sweet chops.
And, in case you missed it, here is Corden, LeBron and Ice Cube in the season finale of Carpool Karaoke.
