The new law isn't going to alter any of those things. In fact there's already a rather badly defined exemption for music at fetes, providing it's seen as sort of incidental rather than the main event (so you can't put on a big rock concert without a PEL, and pretend it's a village fete by putting up a coconut shy).

In fact lot's of things happen which are technically illegal at present, in all kinds of places, and it's just a matter of luck whether someone starts getting stroppy about it. (This is England after all.) The "reform" isn't intended to change that one way or another.

The thing to do though, if you've got questions or are seeking clarifications, is to channel to the officials who are supposed to have this kind of information at their fingertips.

Make them know that someone out here is interested. The more queries they get the better. They might even get some guidelines together, and if they were sensible guidelines they could improve the situation.If they weren't sensible guidelines, they could be a focus for campaigning.
