#4. The Saddest Christmas Song in the World.

Judy Garland met Vincent Minnelli -- her first homosexual husband -- when he directed Meet Me in St. Louis, the movie this song is from. (So you could say that we have this film to thank for Liza Minnelli.)

Apparently the original lyrics were even darker and changes were made to brighten it up a little for the film. But the most egregious change -- "Until then, we'll have to muddle through somehow" became "Hang a shining star upon the highest bough" -- was made later, for a Frank Sinatra Christmas album, and now you hardly ever hear the earlier version sung.

The wikipedia entry for the film is worth a read. The very dry plot summary cracked me up. Here's a sample (Tootie is the little girl, played by Margaret O'Brien): "The emotional climax of the movie occurs when Tootie cannot cope with the disruption of her social world, and experiences a violent breakdown in a yard full of snowmen."
