Cool! I just checked on that, and yeah, Joe D. Grinder/Jody Grinder seems to be a trickster figure from toasts and such, s-thing like Stagger Lee/Stagolee/Stackolee. He always gets the best of guys who are playing by the rules. Previously, I'd heard a rumor that somebody named Jody got on the wrong side of Pvt. Duckworth (who's credited with inventing the cadence, although it seems clear now that it has something to do with the call-and-response field-hollers that contributed to the blues). Guess that won't wash. There were songs by Irwin Lowry and Quincy Jones, one by Merle Haggard (found the lyric for the last, but not for the others -- anybody heard them?)
