Nothing else in your posting makes any sort of sense as it seems to refer to tradition as being "very modern"

Folk & the idea of Tradition is a totally modern contrivance - a very patronising & paternal way of looking at proletarian culture hatched at a very significant remove from the culture itself. It results in a conservative orthodoxy that talks about Tradition though it were a God-given absolute - as Bounty Hound puts it : You have to accept that the tradition exists as that is historical fact, and without that tradition, there would be no new folk music. And he's not alone in believing in such a demonstrable delusion that, sadly, exists to the detriment of a truer appreciation of the phenomenon of so-called Traditional Song in its natural habitat, as oppose to the taxidermy of the revival, and its stars, heroes & emergent volkish certainties.

Otherwise, nice to have a source for the Fish Story. I think I first heard it off Robin Williamson several decades ago and have had it at the ready ever since. I told it to my local priest once, who used it the following week at Mass. There was a one about the fellow who went the hell and couldn't get next to the fire for all the priests - have you got that one too?
