Have you lived on the Planet Zog very long? In a perfect world you'd be right, but this world is far from perfect.

In our case...

1) the house was there before the pub started having bands playing.
2) the level of the landlord's apparent awareness of 'the sensitivity of his neighbours and the community he/she lives in' was indicated by his throwing the fire exit doors, which faced the houses and with the bands blasting away right by the door, wide open - often until midnight (or later if it was a private function).
3) he laughed in my face when I went round and asked for the doors to be closed (on several occasions).
4) the local environmental health authority said they don't attend complaints 'out of normal office hours', and that they don't take any action anyway until they have 'more than x complaints'. (Can't remember the precise number - it was a while ago).
5) all of our neighbours moaned amongst themselves, but wouldn't complain to the council because "We don't want to get involved" - I.e. they feared repercussions.

So I agree with Bridge, there needs to be a strengthening of local authority policing in respect of environmental/noise pollution issues.
