TDBrown and Goxnadly
Scott Graves wrote in a while ago to point out a version by two fellow members of an independent online music guild he belongs to. "St. James Infirmary Revisited" by TDBrown (featuring Goxnadly on vocals), can be heard here. (Later, I also heard from TDBrown himself, who added that the music "is not in the New Orleans' style," and in fact is listed as "Urban/R&B." But that's the fun of covers: taking a song some place new.
Mr. Graves' own music can be found right here.
