The five singing busts in the graveyard scene sing the attraction’s theme song, “Grim Grinning Ghosts.” Though sometimes mistaken for Walt Disney, the face on the bust farthest to the left actually belongs to Thurl Ravenscroft, the song’s soloist. Ravenscroft is known to millions of fans as the voice of Tony the Tiger, the mascot of Kellogg’s Frosted Flakes cereal.
