You're right, Lighter. Talley doesn't even have a chorus. It almost looks like the Talley version is a blackface minstrel song. Some of those verses show up elsewhere in that tradition, I think. It seems like the Brown version has "evolved" a bit, but maybe it went the other way. But that is a definitive line about the "sheep shell corn with the rattle of his horn", along with the the "whipoorwill" line. I think you are onto something though with the Brown version. I have that stuck away somewhere, but as I vaguely recall, there aren't really any more verses, are there? Now that you've pointed it out it sure looks like chanty material.
