Here's the second version from Allen/Ware/Garrison (Slave Songs of the United States), also with tune.

MY ARMY CROSS OVER

My army cross ober,
My army cross ober,
O Pharaoh's army drownded,
My army cross ober.
My army, my army, my army cross ober.

2. We'll cross de riber Jordan.

3. We'll cross de danger water.

4. We'll cross de mighty Myo.

(This) version, probably from Sapelo Id,. Georgia, was sung in Col. Higginson's regiment. On the word "Myo," Col. Higginson makes the following note: "I could get no explanation ofg the 'mighty Myo," except that one of the old men thought it meant the river of death. Perhaps it is an African word. In the Cameroon dialect, "Mawa" signifies "to die." Lt. Col. Trowbridge feels very confident that is merely a corruption of "bayou."


So, Phil, there's something.
