Hope you enjoy! If you hear random noises throughout the video, those were the sound effects from the actual movie when they closed and opened balcony doors. xD
The old Barbie songs actually had a lot of meaning to them. :O I wasn't sure which ponies to do, but I eventually settled with Fluttershy as Anneliese and Rarity as Erika. Still, I don't think I can do their impressions very well anymore when their voice actors aren't singing the song. xD
