The chat show host teamed up with Gary Barlow, Howard Donald and Mark Owen for a charity version of the hit Late Late Show segment.
The British pop trio sang some of their greatest hits including Shine, Greatest Day, and Never Forget.
Corden also helped the band to ‘break America’ – referencing the fact that the group never replicated their success in the US.
“I just think you’ve got to get the word out,” Corden said – before taking the group out on the street.
The group handed CDs out to strangers, took selfies with unsuspecting passers-by, and even performed an in-store gig.
“This is going back to the days of Woolworths and Our Price – this is it,” Corden said to give the band a team talk. “This is the stuff that breaks people.”
While the shop turned out to be a sunglasses store, it didn’t stop the customers from looking impressed.
Elsewhere during the BBC broadcast, Ed Balls revived his Gangnam Style dance in a La La Land routine.
The show has also been plagued by technical issues with viewers complaining of ‘awful’ sound throughout.
