Can anyone help me out with this one? It's a slow minor-key blues tune; I don't recall who wrote it, I heard it first many years ago on an early-70's live record by the Grateful Dead. I have heard it since in a version that sounded more "authentic," but I never got the specifics, and don't remember all the lyrics. The first verse, as I recall, goes something like this:

Death don't have no mercy in this land Death don't have no mercy in this land Comes to your house, but it don't stay long Wake up in the morning, find your children are gone Death don't have no mercy in this land

It's not Shakespeare, I suppose, but sung soulfully against a sort of "blues dirge" it can be very moving. It's not in the DT, so any help would be greatly appreciated. Thanks.
