:::Thanks to YouTube, I've just listened again to Pete Seeger in 1963 and, to tell you the truth, I'm not wholly convinced. He seemed to think it was 'rwm' as in cwm! And a non-native listener could go either way on that one - either towards rim or towards rum! We all agree that both The Byrds and Judy Collins got it equally wrong in the 1960s. And 1960s UK folkie Mick Softley also got it wrong. In 1970s John Denver went straight for rim, even when performing in the UK. As do the Oysterband as recently as last year. Even Show of Hands go for a Seeger-esque rwm. Only Rhyl's Mike Peters of The Alarm seems to get it right. There must be countless other recorded versions from both sides of the pond. The leading rhyme of "give me", of course, could easily sway a non-Welsh singer. A listener mght even think they were the sad bells of Rimini. I wonder how many recordings have it "right"?
