From Old Plantation Hymns: A collection of hitherto unpublished melodies of the slave and the freedman, with historical and descriptive notes by William Eleazar Barton (Boston: Lamson, Wolffe and Company, 1899), page 11, where it is given with musical notation for one voice:


DESE DRY BONES OF MINE.

1. What kind of shoes is dem you wear
Come togedder in de mawnin'.
Dat you may walk upon de air?
Come togedder in de mawnin'.

CHORUS: An' a Lawd, dese dry bones of mine*
Shall come togedder in de mawnin'.

2. If you get dah befo' I do,
Come togedder in de mawnin'.
Look out for me. I'm comin' too.
Come togedder in de mawnin'.


[*I'm not sure how to interpret the notation given here, but I suspect this line is sung 3 times as in Q's example above.]
