The Unbelievable Song for Coke Zero

Cute spot for Coke Zero titled "The Unbelievable Song", what is really unbelievable about this commercial is that it hasn't been seen by the public because it never aired in any part of the world until recently when it just began running in Brazil only.
Quote from Buck Productions:
We finished this spot 15 months ago and it just aired… only in Brazil… but at least it aired! In 2007 Wieden+Kennedy selected Buck to direct this epic rock opera for Coke Zero featuring such memorable cast members as a singing bear, candy-pooping birds, an elk with sausage antlers, g-string wearing antelopes and honeycomb encrusted sheep, among many others.
