Great list, pdq!! Thanks for posting it.

Having said that, with all due respect, I guess I'll be the first person [but maybe not the last person]to quibble over a couple of attributions in that list:

Shouldn't "Amazing Grace" be listed as [words, John Newton, 1779. Music: 19th Century American melody]?

Also shouldn't "Pick a Bale O' Cotton" be listed as [H. Ledbetter, prob trad]?

Best wishes,
