The Living Rockumentary

Love that Andy Williams "Most Wonderful Time Of The Year" but what's he mean about "scary ghost stories"? I am unfamiliar with the traditon of telling ghost stories on Christmas. Seems like a Halloween thing. I mean, I know there's the Dickens "Christmas Carol" but it's not really scary so much as it's a morality tale and that's the only one that I can think of. From mangers to mistletoe to "petards du Noel," I can't imagine what he's referring to. Maybe Henning knows- maybe it's a Weinachten thing.
