"quite obviously"

I don't thing "obviously" is a safe word to use of anything in the music related part of the act.

"Made available" could mean merely being allowed to use, or it might mean something more like, having a room made exclusively available. But if it was exclusively available it would seem that it would have become a private event, and therefore Secton 5.16 could apply - which specifies that "private events are not subject to licensing unless run to provide a profit to the premises manager/owner and/or to the event organiser".

But of course, that's the Guidance, not the Act, which seems to say something completely different.

As I said, "obvious" isn't the word for anything here.
