When Mainbrace were in the U.S. they sang "The Bells of Rhymney" (which they pronounced "rumney" naturally, and paired with "The Old Miner" quite effectively) and at one concert a woman who had lived in Wales commented that she had not heard it for years and now that she had lived there the words meant more to her, for example, the "why so worried, sister, why?" reflected the fact that Wye is so near the English border that it was less affected. I would be very interested in knowing the sociopolitical background of Davies' poem in general and the specific comments linked to specific places in particular.
