During WW2, my dad stood for hours in a long line in Naples, attempting to our an opera house but did not achieve his objective.
I have read Cry to Heaven by Anne Rice, a novel about the golden age of Italian opera and to what extreme lengths society would go to retain their male sopranos (the castrati).
When I was new to the internet I accessed a site that described the grand opera houses of Italy and how filthy they once were. Attendants brought buckeets to the balcony so audience members couild relieve themselves without missing any of the drama. People didnt bathe much in those days. The stench was overwhelming. Vast audiences had no acces to bathrooms and were forced to use dark corners and stairwells during intermissions.
Opera…an elite art form with rough and rowdy origins. I never could find the URL again.
