Many years, I was having guitar lessons off a great chap ( in his 60s at the time), and, for some reason, I sang "Donna, Donna" to him - or at least the first verse. "That song would really suit my wife," he said. And so I supplied him with the lyrics. A few weeks later, I asked if his wife had learnt the song. " O no!" he said, " she couldn't sing a song that mentions cattle being slaughtered!". Interestingly, I've heard " Donna, Donna " performed with the words tethered substituted for slaughtered.
