From National Review Online, The Gospel According To Peanuts:

“We got a call from Coca-Cola,” remembered Melendez. “And they said, ‘Have you and Mr. Schulz ever considered doing a Christmas show with the characters?’ and I immediately said ‘Yes.’ And it was Wednesday and they said, ‘If you can send us an outline by Monday, we might be interested in it.’ So I called Sparky on the phone and told him I’d just sold ‘A Charlie Brown Christmas,’ and he said, ‘What’s that?’ and I said, ‘It’s something you’ve got to write tomorrow.’”

We learned in that American Masters series that Schulz had some ideas of his own for the Christmas special, ideas that didn’t make the network suits very happy. First and foremost, there was no laugh track, something unimaginable in that era of television. Schulz thought that the audience should be able to enjoy the show at its own pace, without being cued when to laugh. CBS created a version of the show with a laugh track added, just in case Schulz changed his mind. Luckily, he didn’t.

The second big battle was waged over voiceovers. The network executives were not happy that the Schulz’s team had chosen to use children to do the voice acting, rather than employing adults. Indeed, in this remarkable world created by Charles Schulz, we never hear the voice of an adult.

The executives also had a problem with the jazz soundtrack by Vince Guaraldi. They thought the music would not work well for a children’s program, and that it distracted from the general tone. They wanted something more . . . well . . . young.

Last but not least, the executives did not want to have Linus reciting the story of the birth of Christ from the Gospel of Luke. The network orthodoxy of the time assumed that viewers would not want to sit through passages of the King James Bible.

There was a standoff of sorts, but Schulz did not back down, and because of the tight production schedule and CBS’s prior promotion, the network executives aired the special as Schulz intended it. But they were certain they had a flop on their hands.

A Charlie Brown Christmas is a glorious achievement. It's hard to imagine it being made today.

I'm thankful that Sparky hung tough, and I hope to catch a showing of A Charlie Brown Christmas sometime this season.

May your Christmas season be joyous and Christ-filled.
