**Thanks to some Japanese fans, it's now clear WHY no-one has a good quality copy of this documentary. Here's the explanation from Japanese fan Reiko:
"During the 1970s before MTV existed, there were not many opportunities to see foreign acts. Of course, there were video tapes to buy, but they were too expensive at that time, about 4 to 5 times more expensive. So, music shops used to rent the "promotion films" (36mm format) from the record companies and then show them to fans at big local halls. Behind-the-scenes shots during their promotional tour tour in Japan were of great interest for the Japanese fans, so it it assumed that it was made by ABBA's Japanese record company , Discomate. I saw this film at the city hall, when I was at high school."
"During this period, the film was rented out everywhere in Japan. But, Discomate went bankrupt in the mid 1980's and since then, this film has been forgotten."
"So, the record company made the 36 mm form film for general use and then they also made a copy on a video tape to secure the product."
So it would appear that somewhere along the line, a video copy has found its way into the fan market and been copied and copied - hence the bad quality that most of us have.
