I don't know if the PS22 Chorus has ever moved me as much as the kids do here, singing this hauntingly beautiful song by the extraordinary Sade called "Pearls." Brielle takes her vocals to new heights,and the entire chorus is simply mesmerizing. I literally cannot watch this without welling up. A new favorite.
UPDATE (2-13-10): Thanks to Ashton Kutcher for tweeting and linking to the PS22 Chorus version of "Pearls" on his Twitter page.
