We have regular classical music concerts outdoors, at the local stately home(Burghly house) we live about a mile away as the crow flys, and if the winds in the right direction you can hear it(ukk), they also have fireworks to go with the music, very large bangs!! , also they have pop bands there like abba tribute , now that was good!and a queen tribute.
It,s only one night/evening now and then in the summer so dosn,t cause a problem, and brings in extra income to keep the house going,along with the horse trials ect.The house runs itself and is not a charity or part of the natural trust ect .
Fair play to them if it keeps the hall going and available to all.
