It'll be interesting to have A Whole New World outside of the princess medley.
One of my favorite things about the old show was that it relied heavily on classic Disney animation- Fantasia, Snow White, Sleeping Beauty, Pinocchio, Jungle Jungle Book, Dumbo, Pan- a lot of which was stuff Walt had a hand in making. Sure, it had Little Mermaid and Beauty and the Beast, but these segments were tastefully done and blended remarkably well with the older stuff.
It's a good sign that they're adding Lion King and Aladdin- both tried and true classics, instead of inserting in Moana, Frozen, etc. because they're the latest big thing.
