Q, you wrote that "The expression "Come day, go day, God send Sunday," is an old one in the Border region of England-Scotland. It also was common in North America"

I remember these two lines in a song as "Go day come day/God send Sunday" but my memory could be faulty or the lines could have been transposed when I first learned {heard} them. There is definitely a tune that goes with this song that I thought assumed was a "Negro" [African American] spiritual, but I can't remember any other lines to it. Has anyone else ever known these lines to be associated with a "Negro" African American spiritual?

I "always" thought that the expression referred to the yearning of enslaved people for Sunday, usually their only day of rest. But I have no documentation that this saying refers to that.

If, as noted above that "come day/go day" is found in an 1883 text, it could have been used much earlier-and thus could have dated from mid 19th century slavery...

Q, you also wrote that "One website notes that Seth Davy was a Jamaican". Is there any mention of his race? Not that the Seth Davy lines are part of my memory. I only have the slow tune, and those first two lines. The other lines in that Whiskey On Sunday song are not at all familiar to me.
