Well, there's some cast & crew comments culled from various sources on the StarWarsHolidaySpecial.com website, as well as the Fox News clip and TVLand "100 Unexpected Moments of Sci-Fi" clip. Or perhaps you need the caption of Boba Fett's 1980 toy pre-release caption that mentions the HS in this article. The script and BTS phots are on there, but I assume you already have them.

And if you want something terminally bad, go find the review of the "Christmas In The Stars" album on X-Entertainment.com, grab the title track and have it play over the end credits. BWA-HA-HA!

There is a fan-made set of Chewbacca's family on this site. A curiosity, but it's something.

And if you need a picture of Steve Binder, there's a small picture of him here. It's for the Elvis Comeback Special, but he was the director of that in addition to his work on the Holiday Special.
