James Corden And Sean Hayes Bang Out Justin Bieber’s “Sorry” On A Giant Piano

But first... A little "Heart and Soul."

Ahead of next month’s big James Burrows tribute special, which will feature the reunited casts of Will & Grace (sans Debra Messing) and Friends (sans Matthew Perry), W&G OG Sean Hayes is getting into promo mode Bieber-style.

Hayes joined Late Late Show host James Corden to give Justin Bieber’s mega-bop, “Sorry,” the Big treatment, with the two pounding out the notes on Corden’s “brand new toy,” a giant piano.

They warmed up (and winded themselves) with a bit of “Heart and Soul” before upping their street cred with something “hip, down and groovy with the kids.”
