Since taking over the Tonight Show from Jay Leno, Jimmy Fallon has brought in a host of stars to sit down and goof around with him in the studio. Last night was no exception as singer Billy Joel stop by and the pair form an improvised Doo-Wop group using nothing more than an iPad app.
They got a bit of help from The Roots to really bring it home at the end but for only mixing it up on the spot with an iPad even Tim Cook himself was impressed.
Check this out. @jimmyfallon and @billyjoel with iPad and a cool app called Loopy HD. Magical. https://t.co/dWlZr6Lsm6
