The Lincolnshire Folk organisation has been asked to organise a day of folk music at Burghley House (Big Flash Stately Home) in the spring. We thought this seemed to be a good idea and we have enough performers available to fill the day and give a high standard of entertainment. Everyone will be giving their time freely. However it looks as if this will not actually happen because all performers have been asked to provide a copy of their Public Liability Insurance documentation.
Is this reasonable?
