Well I take your point but let us not praise the UK legal system too much.

S 182.1 of the Licensing Act 1964 makes an apparent distinction, allowing 'public entertainment by way of music and singing only which is provided solely by the reproduction of recorded sound, or by not more than two performers, or sometimes in one of those ways and sometimes in the other.' Presumably those who drafted this nonsense provision believed that, under the law, the word music did not necessarily mean singing (and presumably vice-versa?).
