A further point for Richard B.

He is correct in indicating that, when the relevant minister, gave confused and inhelpful answers to many questions. You don't need to read much parliamentary debate to realise that misunderstanding of the subject or document under discussion is the norm. However, it is not what is said that matters, but what is printed in the law. The total law about incidental music is:

The provision of entertainment consisting of the performance of live music or the playing of recorded music is not to be regarded as the provision of regulated entertainment for the purposes of this Act to the extent that it is incidental to some other activity which is not itself-

(a) a description of entertainment falling within paragraph 2, or
(b) the provision of entertainment facilities.

That seems to be pretty wide. Let's start to list some activities that are not covered by a or b above: Selling underwear in a shop, going up in a lift, Performing a Morris Dance (actually mentioned in debate), Selling bottles in a supermarket, selling coffee in coffee bar, selling beer in a pub, performing a play (also mentioned in debate). Can Richard indicate anything in any law that divides items in that list into different categories or explicitly states that any of them fall into category a or b?
