Just adding this bit as I happen to be going through some old notes:

Clarence Marie, a 25-year-old Black longshoreman of Yarmouth, Nova Scotia, was noted to sing this:

Steamboat comin round the bend,
‘Way down in Georgia
Loaded down with colored men,
Hold the woodpile down.

My source is 1931's Folklore from Nova Scotia by Arthur Fauset. However, Fauset worked in the field with anthropologist Elsie Clews Parsons, who is the one that noted Marie's song. A quick search of collections of her work suggests that Parsons did that work in 1923, though I haven't rigorously verified that.
