The landlord will not be convinced that he should be a bit more circumspect. He is going ahead with the gigs regardless of the fact that he is under scrunity. The band will appear dressed as painters and decorators. If there is any hassle, we will set about emulsioning the walls and glossing the interior woodwork. If they notice the PA, this is merely De-Mister's stereo. Any instruments present will be explained away as ornaments, removed from the wall whilst it is painted.
I think that's everything. He will receive a visit from the council tonight, I just know it.
