Adele belts out ‘Hello’ with classroom instruments on Jimmy Fallon...

It was more entertaining watching Adele doing everything she could not to crack up while singing 'Hello' with classroom instruments.
She received assistance from Jimmy Fallon and in-house band The Roots. Even with the struggle straight face, Adele's vocals remained impeccable. In more astonishing news (it's never ending), Adele is set to pass the 3 million mark in Stateside first week sales with her new album '25.' In the UK, it has already sold 681,019 copies. Say what now?!?!
