I love Its A Charlie Brown Christmas but my favorite is
The 1970 Santa Claus Is Coming To Town. Its actually rather scary and could be traumitizing for young kids. Burgermeister outlaws all toys on threat of dungeon, he puts Kris Kringle in a dungeon. He confiscates all the toys. Plus the snow creature that harasses Kris Kringle.
I cannot recall last time it was on CBS it used to always be on although they did cut at least one song Sit On My Lap, yeah sounds creepy. Although I cannot recall the song. I should try to find it.
