I don't recall who wrote it but it went something like this:

Mix me a julep and kick me a hound And we'll all say, "Yassuh, yassuh yassuh" We's gwine dig a hole in the cold cold ground For Mr. and Mrs. Massa.

Actually, songs like Mass's in the Cold Cold Ground are interesting in that they express sentiments that were common when they were sung: not necessarily what the slaves thought, but what people THOUGHT the slaves thought.

When I first drifted into folk music, you couldn't say "Black"; explicit sex was PI; Rudyard Kipling was a no-no; Songs about wife-beating were OK. Times, and politics change.
