LAs will feel they can obstruct and prevent social music making like sessions etc, under this Act simply because they always have..

Bit of a sweeping generalisation I'd say. In fact there have been hundreds probably thousands of sessions which have been ignored by licensing authorities over the years (accepting the legality of the two-in-a-bar rule)that have been illegal.

All the carol sessions in Sheffield were decidely illegal. Virtually all sessions at folk festival fringes were illegal. So to say they always have obstructed is patent nonsense and as is often the case generalising from the particular does your case no favours. Please - if you would be so kind Roger - if you don't mind that is - no pressure you understand - feel free to do as you like - try and write with a modicum of thought.
