Taking to the Tonight Show Music Room (which looks like a standard green room in disguise), Adele and company slowly build up Hello with a selection of kid-friendly instruments.
Adele, of course, takes up vocals and flip phone duties, while Fallon slowly finds his feet on a block of wood, a bass drum and a Casio keyboard.
As for The Roots, their musical talents are handed the kiddiest of instruments — we’re talking a colourful xylophone, a ukulele, kazoos, a banana shaker and some bongos.
Hello recently became the subject of a string of brutal re-imaginings in styles ranging from black metal, folk and dream pop, but Adele, Fallon and The Roots’ version is a little more kid-friendly.
