You did better than I did in searching for it. I tried every permutation of lyric in google. I was hoping it was something my Gammy (grandmother) had composed and taught to my Mom. Ahh well. I know the tune but as I don't read music I cannot get it down in print.
I have been trying to catch up with my octagenarian Mom (very busy lady) to ask her about it. I am thinking it is something she learned in school (Virginia) in the mid 1930s to late 1940s. If I learn more I will post it.
