I have also read widely online (Fiddle Hangout, Traditional Tune Archive, etc.). Though not included on the Highwoods Stringband album previously referenced, others have reported that band member Kenny Hall sang the verses often, and cite his recording on his eponymous release (Philo 1008, released 1974, track A6 - listen), though sadly the recording is instrumental and the liner notes make no mention of our nocturnally-locatable children.

The Tune Archive link above adds the following notes:

Sight handicapped mandolinist and singer Kenny Hall learned the tune when young (c. 1940's) in Texas from a woman named Clara Desmond and the Desmond Family of Texas. Said Hall: "She was the piano player. She kept that steady rhythm. She made that band keep a steady rhythm, too. Not too fast, not too slow. She was kind of the rhythm base of the family. Oh, she was a lot of fun. She didn't like drinking, but she would allow it as long as you went outdoors to do it." An alternate title, “Feed Your Babies Onions,” is sometimes employed for the tune, derived from Hall who sang these words to the first strain:

Put bells upon the sheep so the blind boys find them in the garden after dark,
Bells upon the sheep so the blind boys find them in the night.

Oh, feed your babies onions so you can find them in the garden after dark,
Feed your babies onions, so you can find them in the dark.

Hall explained the words were made up during the Second World War, after the Red Light district nearby was shut down. Sheep had replaced the interred Japanese gardeners to keep lawns groomed, said Hall, leading one old German factory worker to suggest the bells might be useful to those 'visually challenged' who were in need of relief.
