My apologise for not remaining in the thread of things, had to go away!   But, not being one for all this chat thing I didnt realise that so many people would actually bother to read, let alone answer my question.   Many thanks for your replies. I have had an answer from the local police office in charge of licencing, who assures me that after asking his "learned friends", that I will not need to worry about any licencing because this is a private party, not open to the public . But the organisers should be concerned about the Noise problem with the neighbours, which seems a reasonable remark. The gig is in July, I shall let you all know in due course the outcome. In the meantime I shall follow the thread.    Regards
