Make Music at the tip of your hands! #loopy #tonightshow

So I was on Hulu the other day, taking in an excellent new episode of the Tonight Show starring Jimmy Fallon.  It was classic Jimmy; funny monologue, “thank you notes” and of course The Roots, followed by guest interviews. I usually never listen to the guest interviews, but in this case I am so glad I did.  In this episode the guest was Billy Joel, and together with Jimmy he created late night magic!  The two stars performed a duet using an iphone app that loops voices, and I have to tell you guys it was pretty sweet!
