It looks like there's a completely different spiritual also called "Religion is a Fortune." It's in "Hampton and Its Students. By Two of Its Teachers, Mrs. M. F. Armstrong and Helen W. Ludlow. With Fifty Cabin and Plantation Songs, Arranged by Thomas P. Fenner." at Documenting the American South Page 189, this file is huge! It does have music.


[Oh, religion is a fortune, I raly do believe,
Oh, religion is a fortune, I raly do believe,
Oh, religion is a fortune, I raly do believe,
Whar sabbaths have no end.
Whar ye been, poor mourner, whar ye been so long;
Been low down in de valley for to pray,
An' I aint done praying yet.]
