Well, fwiw, personally I think it could well've been both. If it was one or t'other, I agree with your views & largely for the same reason.

Not saying yr wrong, but I can't say I noticed that the midsummer was 'favoured' by the prog - other than that midsummer was what was being celebrated at the time etc. Both midsummer & midwinter were certainly mentioned & the possibility of it celebrating both too.
