So who goes to these events? Must be Expat Northerners in London? Would these be the same people who cannot be bothered to watch the Broncos when it is the best value and cheapest pro elite sport in London they would rather watch the game on TV in a pub.
When I was an expat Northerner in London, I think I watched the Broncos/Quins about six times in almost ten years. On all but one of those occasions, they were playing Huddersfield. Just because I had moved to London didn't mean I changed the team I support.
I did watch the Skolars regularly, but I doubt I would have done if they hadn't been two divisions below Huddersfield.
And yes, I did used to go to all sorts of events and exhibitions when I was in London. If you're the kind of person who reads the listings magazine on a Sunday and thinks "Ooh, an exhibition on the political implications of cartographer...sounds interesting", then you'll find stuff to go and see wherever you are. If you just want to stay home and watch X Factor, that's fine, but you won't then really see the benefit of living in a big city like London.
Incidentally, there is a very active cultural life outside London as well. In fact, I think it's probably better because it's more inclusive in the sense that it usually seems to involve being active in it, rather than being a passive spectator.
If there must be trouble, let it be in my day, that my child may have peace.
