But thank you for making my point. The public licensing of streets and open areas - as if they were premises that did have occupiers and licencees - has only increased restrictions on entertainment that can take place there

Nothing posted by either myself or by snuffy has made your point at all. Far from it. The licensing of some of the streets of Sheffield has made no difference whatsoever to how much music is made on those streets. The fact that you fail to understand and/or disagree with the point we make does not make it invalid.

As for it being an afterthought how do you know? And anyway if it had not been in the Guidance which as you know has no statutory function, what was to stop a council licensing streets or other open spaces?

As far as I am aware and I am sure that I will be corrected if I am wrong - the moving vehicle exemption was an old one (like the one for garden fetes) that also applied to PELs and would have enabled carnival floats to be exempt

You are - as far as I know - wrong. The moving vehicle exemption was included specifically to allow the Notting Hill Carnival to go ahead.
That came from a civil servant involved with the drafting of the legislation.

There is no mention of moving vehicles in previous PEL legislation that I can find.
