I'm genuinely curious.
Talk:Great Dickens Christmas Fair
I hate to say it, but I think not.
I suppose that this is most like our pages on Networks, insofar as it's a thing that produces other creative works like musical performances. Would Coachella qualify for a page, or Sundance? This feels like it's right on the margin of being on-topic, but also mostly harmless.
By that measure, yeah, I suppose it does pass the threshold and merit documenting.
I lean towards keep for the same reasons as Labster.
What can it be categorised as when?
I suspect we'll need to create a new category for this kind of thing, something that would also incorporate Networks, as Labster notes. Hm. "Venues" might be the specific sub-category for this and maybe individual theaters of import, but I'm currently drawing a blank on a good name for the super-category.
It does look like both an event and kind of format for performance.
