Hey, It's That Voice!: Paul Frees, voice of Ali and the Magi, as well as assorted other minor characters, is probably best remembered as Boris Badanov from Rocky and Bullwinkle, and is also the "Ghost Host" from Disney's Haunted Mansion rides.
He's also Toucan Sam. Kinda puts a new spin on the story: "How do we get to Bethlehem? Just follow my nose!"
June Foray, the voice of Rocky and Natasha Fatale, is Aaron's mother.
Screwed by the Network: The DVD and Blu-ray Disc releases feature an unreleased stereo soundtrack that was added during restoration of the special. Unlike the orginal mono mix, this mix leaves out a number of crucial sound effects, most notably Aaron's drumming sounds and the crowd commotion during Aaron's performance at Jerusalem.
Talking to Himself: The Three Kings and their servant discussing how to replace their weary camel — are all Paul Frees.
