I just saw the old Box Office in the hall of Canadian Opera Company and I also found a plate of appreciation attached right beside thanking for donation for making the old ticketing booth stands still in there.
Opera business has been suffering from the bad cash flow of less and less number of audience and lack of financial sponsorship from the big corporates. Actually all the classic genres of music or performance have similar financial issues.
It might be the time for the people in classic world to renovate whatever to stand viable again in the art industry. Hopefully not too late..
