Jimmy Fallon, The Roots and whomever they choose to bring into their musical funhouse have brought us some of the more enjoyable, fun-filled musical moments on late night television (if you don’t believe us, check out this with Carly Rae Jepsen).  Since it’s Friday, we’ll look past our Billy Joel “meh” and invite you to view the performance last night on The Tonight Show by J-Fal and Joel, with assistance from the iPad app Loopy HD and The Roots.  All in good fun.  Check it out.  And then get back to being serious and overwrought, will ya?!
