It's not "either / or", it's "not only / but also".

Of course it's important to try to ensure that pubs get their licences to cover live music as well as selling drinks, but that's not enough.

There are going to be pubs which don't do that, for various reasons, and we want to make sure that that isn't the end of it, but that it is recognised by the pubs and the local officials that licences aren't needed for music in some circumstances. And that particularly applies in the case of possible venues which are not pubs, and which are not in the business of selling alcoholic drinks in the first place.

People keep on slipping back into this daft and lazy assumption that the only places where live music can possibly hapen is in pubs.
