How about the movie, "The Ghost and Mr. Chicken" starring Don Knotts.
As I recall, there is a haunted organ in the movie. I don't have a
copy of the movie, but I seem to remember that this was a large console
organ. (Does anyone know if this organ console was a legitimate
console or a prop?)
[ I'd bet "dollars to donuts" that it's a prop. The studios wouldn't
[ want a heavy organ console to transport, and besides, the art
[ director must earn his pay by improving the looks of the props.
