O.k., had some time on my hands and went looking for gospel examples, but have come up pretty dry. But, here's an assortment of stuff from my Googling about --

This chapter by David Evans: "High Water Everywhere: Blues and Gospel Commentary on the 1927 Mississippi River Flood" (in Nobody Knows Where Blues Come From: Lyrics and history, edited by Robert Springer, Univ. Press of Mississipi, 2006) is said to be the authoritative thing to read. Unfortunately, Google Books (which I linked) doesn't give the whole chapter and happens to quit just as he's getting into the meat of it. However, the cultural/political background is there and is quite interesting, and it does get to a list of items he says are not from the 1927 flood -- but that's o.k. for us!

Here's what there was:

"The Old Account Was Settled Long Ago"
Norfolk Jubilee Quartet, 1927 (Paramount 12499)

In refugee camps, whites sang "Jesus, Lover of My Soul" while blacks sang "Swing Low, Sweet Chariot"
