The French airing is legitimate. I saw it back in the day! There was much talk about it the day after at school! We were young, obsessed with Star Wars, and we were hungry for more: an hour of Star Wars, on TV, was quite the (pleasant?) surprise (I think I caught it by chance!). There wasn’t really a lot of content to consume in France 40 years ago: imagine, we only had 3 national TV broadcasts, and no local ones! So any new Star Wars (especially free on TV) was welcomed with enthusiasm!
