Here In Devon, at least, the apples and cider related verses are more usually associated with apple tree wassailing rather than any kind of Christmas or new year house visiting tradition, I wonder if the two traditions have become conflated by some singers or collectors, leading to confusion between two different rituals both called wassailing I'm not sure that there is a great tradition of cider production and drinking in the Gower district, but certainly in many parts of Devon cider making is still widely carried out.
