I was just sure someone would post this before me. I'm almost never the first with info... Wow, to feel useful!
The set list includes:
Haunted Mansion's Grim Grinning Ghost
This is Halloween from Nightmare Before Christmas
Fantasia's Night on Bald Mountain!!! and
Jafar's Theme from Aladdin
I'm really excited about this show! I almost never get excited about the fireworks at TDR, but this might be awesome!
