Camden Council imposed new licence conditions in response to 23 complaints from local people for the 2006 concerts, resulting in the season becomming lossmaking. As a result, English Heritage has just announced that these concerts will no longer continue in future years. It is notable that the majority of the complainants moved to the area after the concerts begain 55 years ago.
English Heritage has started an online petition to Camden Council, which I would urge you to sign.
