It is disgraceful the Council doing this so close to the date. I'm sure they have had plenty of time to do risk assessments. I wonder what their grounds are for revoking the licence? Will they make a statement? Maybe they think it's got too big, if so they should say so.
We went to the Hounslow festival once but actually preferred the Milton Keynes festival because access was better, lots of parking and it's got a good "amphitheatre".
