Presenting... the September 4th, 2000 prototype of Spyro: Year of the Dragon, a SCEE review build. Some may remember that a review build that released before was originally designated the same name - this is a different build to that one, and has many more differences.
Here's a comparison of all of the cutscenes in this build, the September 11th prototype, and the final game. I've tried to match them up visually as close as possible. The audio playing is the September 4th build only.
