I was born in 1965, and i'm very familiar with these. They are definitely part of my childhood! Rudolph the Red Nosed Reindeer played every year on CBS, I believe, and I would lay in front of the television. the Christmas tree was next to the tv, and I would lay there and watch Rudolph. I loved Clarice and her voice so much! As far as my memory goes, Santa Claus is Coming to Town was always shown either the same night or the next night. And while i enjoyed The Year Without a Santa, it doesn't hold the same fond memories, although I do love teasing my brother and calling him Bubby Meister Meister Bubby (if you've seen it, you get the joke). I own the first two on cd and try to catch both every year.
My absolute favorite is The Little Drummer Boy (1968). It's about a boy named Aaron who's family lost their lives in front of him and he grew up resenting people, but he loved animals and especially a lamb. One day he was kidnapped and forced to preform. While the group was traveling to Bethlehem, the lamb was ran over and appears to have died. In tears, the boy played his drums for the babe in the manger, and the lamb was revived. i cry every time I watch this. Highly recommend it. I have it on cd as well.
