Interesting discussion... How about 'My Son John' about a soldier who returns from battle having lost his legs?
The Jones Boys sing a version of this song that you can listen to on Bandcamp - https://thejonesboys1.bandcamp.com/album/like-the-sun-a-glittering
And they've got some writing about the tune and posted the lyrics on their own website here https://thejonesboys.org/lyrics/my-son-john/
