But I thought that the whole idea of the act (and the guidance document) was to ensure some uniformity in the way that it is applied across the country.

In practice what is going to happen is that local authorities are going to come up with their policies, and some of these are going to be used as mode la for other local authorities, and some are going to probably get struck down as illegal. From what I've hear of Greeenwich I think there should be a good chance that they will fall in that latter category.

but at least 90% of the places where I'm involved with live music these days is in pubs (even at most festivals)

That's quite true - but if you cast your mind back to the days if long ago, it used to be commonplace to have live music, folk music even (skiffle that is) in coffee bars. A change in the law ended that, more than fashion; the fact that it's effectively only pubs now reflects the legal situation we've been living in for the last forty years. I'd like to see us get back to a situation where live music happened in a wider range of places.
