Don't be sad Alea - just be happy that you had that opportunity; and the wonder of television means that we can have concerts in our living room - it is a miracle that I lose myself in every summer - wonderful! I just love it.
My DD and her OH earn their living by putting on 6 outdoor orchestral proms concerts each summer in the grounds of stately homes, with cannons, cavalry displays and amazing fireworks - and a spitfire flypast to music. It has been a real sell-out this year. They had to close the gate when one concert got to 10,000 people - just no more room! My little DGSs love it - they go backstage and see the instruments, and help with laying out/taking down the barriers and the cannons in their little hard hats. So they get to hear the classic last night items like Jerusalem 6 times every year - my 6 year old GS talks very knowledgeably about the classical items and which he prefers - they are very lucky children indeed. They also run a wonderful day folk festival and again the GC meet the performers and help out behind the scenes - they just love it!
