This song (not a blues song) is quoted in Ralph Ellison's Invisible Man (1952, chapter 18):
"Don't come early in the morning
Neither in the heat of the day
But come in the sweet cool of the
Evening and wash my sins away..."
(From: HERE)
Also in UNCLES JOSH'S PUNKIN CENTRE STORIES by CAL STEWART (1903):
Samantha Hoskins concluded she would have to sing her favorite hymn; it went something like this:
"Oh you need not cum in the mornin',
And neither in the heat of the day;
But cum along in the evenin', Lord,
And wash my sins away.
Chorus-- Standin' on the walls of Zion,
Lookin' at my ship cum a sailln' ov{er};
Standin' on the walls of Zion,
To see my ship cum in."
"Standin' on the Walls of Zion" is in Carl Sandburg's The American Songbag (1927, p. 484, with music; Sandburg says this is from "white man's spiritual"):
Then it's a hooraw, and a hooraw,
Thru the merry green fields, hooraw!
Standin' on the walls of Zion, Zion,
See my ship come sailin', sailin',
Standin' on the walls of Zion,
See my ship come sailin' home.
