Thought I might mention that this documentary grew legs and is having its world premiere at SXSW 2023 in Austin this Saturday. I actually connected with Steve via this thread and became a co-producer on the film, working with him mostly remotely over the next 5-6 years on this. It’s become the definitive documentary on the subject, with interviews conducted with nearly every living person who had anything to do with the Holiday Special, as well as a few who didn’t.
Here’s a link to the SXSW site for the film:
