This audio adventure is called "The Human Factor", which was one of the newer stories created specifically as a tie-in to the 1979 movie. It was issued on a couple different multi-story LPs as well as this single with the dull as dishwater sleeve, seen above. Somehow I had overlooked posting it before so it is making its debut on the site today!
As an audio drama, "The Human Factor" is on par with the others from this later series of recordings. Though I did particularly enjoy the oblique references to the other stories in the opening moments of this one (continuity!).
By the way, if for some reason you need to own ten copies of this record, there's a guy on eBay who can hook you up.
Thanks again Rockwell!
