Pony and the Beast-Days in the Sun

After much debate, I finally decided on who would take the roles of Madame de Garderobe and Maestro Cadenza. For no reason at all except for the fact that they play piano and the fact that they're always together. More clip-based than personality-based. See, in the Broadway set I had Granny Smith as the wardrobe, but that clearly wasn't going to work here, and every other pony/human playing piano either already had a role or didn't show up in Equestria Girls.
Since we have no young Sunset Shimmer, I used Sweetie Belle as the younger version of the prince, because at least in black-and-white, Sweetie Belle looks similar to Sunset.

Cast:
Belle - Twilight Sparkle
Beast - Sunset Shimmer
Young Prince - Sweetie Belle
Beast's Mother - Celestia (closest thing Sunset has to a mother figure)
Cadenza - Bon Bon
Madame de Garderobe - Lyra
Lumiere - Applejack
Plumette - Pinkie Pie
Mrs. Potts - Fluttershy
Cogsworth - Rarity
Chip - Apple Bloom (I know Chip doesn't exactly sing here, but I need to explain one of the flashbacks)
