The muses appear as the Haunted Mansion's singing busts, backing Megara as she sings "I Won't Say I'm in Love."
The Haunted Mansion attraction is located at Disneyland, Walt Disney World and Tokyo Disneyland. Instead of the Haunted Mansion, Disneyland Paris has the Phantom Manor and Hong Kong Disneyland will have Mystic Manor.
