I used to try religiously to watch Omnibus every week. As the series ran for many years, I obviously missed loads of them. In addition to the ones on David Bowie, Leonard Bernstein, as well as programmes on classical composers, I particularly remember the one on Edith Piaf. She'd been dead for a couple of years before I had my first sojourn in France but she remained ubiquitous in a similar way that Um Koulthoum still is in the Arab world. I came back from France with a heap of EPs and LPs of her.
So when it was announced that this Omnibus edition would be about her, I made sure of tuning in. Over fifty years later I remember little except that I was transfixed. I do have a memory of her performing Milord in the programme and clearly having a great time using the whole stage as a prop. IMDb tells me Charles Aznavour appeared but I don't remember that. I wish I did.
I'd love to see this again. In black and white!
