Achilles,
Not sure here, but I'd asssume that you're referring to the old New Orleans classic "Jock-A-Mo". It's been covered by most of that N'awlins Blues crew - notably Dr. John. James Booker does a great version, too. Since I can't summon the Dead's take in my head, I'd only caution that these versions are piano centric and bark up a very different tree than most of the Dead's material.

PS If it's a different tune, please disregard the above with my apologies.
