I'm pretty sure it would be impossible for me to be anymore proud of JR when he plays the piano.
The way I carry on you'd think he was recital-ing at Carnegie Hall, and not St Mark's Episcopal church.
His teacher is leaving for 3 months to go play on a cruise ship, which, of course, JR thinks is the coolest thing he's ever heard. (Hence the reason for a recital in November.)
And if you want to hear the virtuoso/child prodigy/pianist at work, here you go.
I'm pretty sure the tongue wag is just another sign of his piano genius.
