Nice to discover this thread, bringing back memories. First version I heard was the Byrds', pronouncing it wrong of course, but I knew no better till I asked my schoolmate's Dad, who was Welsh, and he promptly went off into raptures about the Rhymney Brewery!!
Ah, poetry indeed (chortle).
Thanks also for posting full lyric, as I too had missed out on the second verse. So a bit more learning to do.
