What a splendid thread. Perhaps, some of you can help me recover a few of my favorites. There was one sentimental tribute to a rural physician called "Doc Brown Has Moved Upstairs".
It's years since I heard that one. I'd love to learn the words.
I had a copy of The Bab Ballads when I was a kid. I loved called "The Fairy Curate". The last line said that the protagonist "... changed religion like a pidgeon and became a Morman." What a rhyme!.
