I think some people dancing on a street corner in the 40's and 50's is a far cry from the junk you see today. Given that this was before plastic was commonplace I doubt there was too much persistent litter, and if someone pees in a bush I don't really care.
Maybe, but what I'm saying is that, if they were to do it today, as the parent comment wistfully longs for, that would be what the locals have to put up with.
