Okay, I wanted to wait to upload this since I just put up a video a few days ago, but if I don't put it up now I'm going to keep editing and re-editing it until I go blind. I think I may have become mildly obsessed with getting it exactly perfect, and that way lies madness.

Edit: Title changed from Pony of the Opera to Phantom of the Gala after seeing the suggestion on EqD.

Song is Masquerade from the 2004 Phantom of the Opera film

Video is from My Little Ponies: Friendship is Magic
