Scottish Chamber Orchestra

We listened to this Orchestra in Aberdeeen Music Hall. There was Walton and a Barber cello concerto that I'd never heard before. We were in the balcony and a bit alarmed by the silver haired audience below us. What will happen when these folk stop going to classical concerts? Is there another generation maturing into it or will the halls fall empty? The Killers were also playing Aberdeen ladt night so maybe that explains the missing demographuc at this event. Apparently they were great too.
