Thank God. (Sort of.)

That's a damn good question. But maybe not, because it's not officially out in America AFAIK, and that video is a live performance, not the studio recording.

Two things:
(1) No editing, no lipsynching. That's a live performance on live television.
(2) Boing Boing had it wrong - that's the performance at the final, not the semifinal. The semifinal was less elaborate, and didn't have the drummers hanging from the wall.
