Once again, I've stumbled on Robert Palomo's excellent rendition of "Cape Cod Girls." He plays it very tastefully and sings really (really) well. I asked about tablature for this song about three years ago and Robert replied that he didn't use tab but plays banjo by ear.
Here's his youtube clip of the song:

In the intervening couple years I've gotten better at clawhammer and am trying to play the song again. I think he plays it in Open C tuning capoed up two frets to Open D, but I might well be wrong on that. (Could it be in Double C?)
Anyway, Could anybody tell me the tuning for sure? Anybody know of any tablature for any version of this song? As always, thanks for your help. (and thanks, Robert, for the great song)
