If you watch the right side among the spectators, you'll see about a dozen somewhat older folks singing along, including the call and response, and in other ways showing signs that to me make me think they used to perform this themselves.
They may not be up to it any longer, but it's still of importance to them.
Which was a very nice thing to see.

...Or there may have just not been enough space in the venue to include them...
