Can someone identify where Crosby Stills and Nash are singing “Teach your Children” in the linked video?
At the start of the clip, they’re seated and it looks like they’re indoors on a stage in a theater or studio. Then at 2:24 it changes; they’re standing on an outdoor stage with a huge crowd.
One of the comments says “I was there at the Rose Bowl!” Is that the location of the outdoor performance?

There’s a comment on this reaction video that says, “That last bit, with the massive audience, was a surprise performance by CS&N at the Live Aid-leg in Philiadelpia, 13th July 1985.”
