Had a look at that video a few days ago.
I have a feeling that what we’re calling the “original” version is actually more a workprint than a final print; some music cues and sound effects are absent and at one point, when Charlie Brown realizes that Snoopy is decorating for a “lights and display contest?!”, his voice is not provided by Peter Robbins. Is there anyone out there who can do a reconstruction of what would’ve aired on CBS less than 55 years ago?
Additionally, the music was recorded in stereo, but downmixed to mono on both the workprint and the broadcast prints. Anyone here willing to sync the stereo score elements (most of which were released on CD and vinyl) to the video of the official Blu-ray release - or their own restoration/preservation - of the special? Here’s a very useful cue chart.
