This is somewhat of an oldie — February ’05 at the 9:30 Club, available on Pancake Mountain DVD #2 — but it was just added to YouTube and is definitely worth your while. It opens with the tail end of Flaming Lips and Hesta Prynn getting cheery with “Daydream Believer” then segues into the Arcade Fire performing “Wake Up” with a bunch of kids dancing around their feet.

Summer’s been canceled! Glad no children were hurt with all those percussive instruments being passed around.
