@quid I'm not entirely sure why I was so smitten by it: the music is wonderful, but also, the video of spectators, and their reactions, and the spontaneous joy of the children add a moving touch. And the spontaneity of it all.
It's one thing to go to a concert where you expect to see and hear exactly what brought you there. But how wonderful to be out and about, with no expectations, to see and hear the music come to you!
Anyway, there was a user that posted to meta earlier, who has been rather problematic, in their subsequent actions on two questions they asked, and further questions, and their comments. I'd be happy to say more privately, but I do not want to name names here, @quid. No one action has been what I would consider flaggable, but the sum total of their disregard, across a number of posts, presents a problem.
