I'll try again to do the sound in a better quality, the recording is complete right from the beginning but the commercials were removed during the recording, that's ok because there's a picture of the Wookie treehouse after each commercial break so none of the footage of the special itself is missing, well maybe one second right at the end credits. So far without doing anything special and recording out of a average VHS player to an old capture card the video looks about the same quality as the WMAR 2 or KCCI screenshots I saw on page 22 of this thread, although the colour on my copy is better than the WMAR 2 because it's without the "NTSC Redness". I think the potential in the tape is better if I had better equipment.
I'm willing to loan the tape to someone than can do a proper job of capturing it if this tape is deemed worthy of the effort.
I'm sure at least in my location it only aired the one time on Channel Win TV and that was around 1980 or 1981, which was the only channel I had that aired it (I never had Channel Ten in those days)
