Wanamaker's Christmas Light Show

my parents took me to see this when I was very young - I have a hazy memory of a big dark room with a huge tree and 2 dancing snowmen (see 9:45) on a whim I looked it up and there it was !  From what I understand the show didn't change all that much over the years - but at some point the original narration by John Facenda was replaced by Julie Andrews . . . Wanamaker's sold out to Macy's a few years ago, and the store is now closed - I am not even sure they do organ concerts anymore . . . but I can say I did see this in person back in the early 70's !!
