Which song is the "deedoo deedoo, deedoo deedoo"? It was the song played as Atreyu approached the mirror gate, and echoed throughout the film when Bastion read the book. Is Magic Mirror the name of a later song? Thought Henson was alive when the film released. I was never sure to what extent Henson helped make this film. Surely the luck dragon and rock giant were works of his company, at least I always thought so. Uncredited?
