the most likely answer.
@PeteF3, They were taping at least specific matches in Chicago for clips in 1985 (Martel vs. Hayes, Martel vs. Roberts are the two I first think of from that time frame). I know at least one guy that was in attendance for Flair-Robinson and he didn't seem to think it was filmed as he saw no cameras, even in the place they normally had one for the odd Chicago clips they would show on TV. Same for Bockwinkel-Wanz, unfortunately, which doesn't mean either wasn't filmed of course, but if they did it wasn't obvious.
