Music is THE universal language. Thanks for sharing this. And I must recommend the Virtual Choir TED link on the SippicanCottage post, btw (via julie commenter). Thank you, God, for giving us the ability not only to create harmony but to be deeply moved by it also. And thanks Gerard for sharing this. The world sure needs more of this right now.

Hmmm.. what would you call this. They are original works, and yet sampled bits of others video.
It's quite impressive however you call it.
