The TV special "A Charlie Brown Christmas" from 1965 is a classic. (I was born in 1965...does that make me a classic?) As far as I'm concerned, it's the best that TV has ever had to offer during the Christmas season. It mocks commercialism, has some cool piano jazz music, and ends with a recitation of St. Luke's account of the birth of the Savior. How can you beat that?
Thanks to Gene Veith for linking to a great article about the cool music you hear throughout the show.
By the way, the Peanuts theme is called "Linus and Lucy." It happens to be in my own piano repertoire and has a soft place in Julie's heart...it's the first song she ever heard me play on the piano. Funny, though...I don't remember her swooning over me while I played like Lucy did with Schroeder!
