gCGCD, relative (aka Double C, One-Finger C or Hook & Line tuning).
I learned this song from George R. Gibson of Knott County, KY when I was very young. He sang both "Black Bottom" and "Stagolee" for me to this same tune. Much later in life when I was in my 20s I heard John Haywood play the song differently--in this video I describe how I heard each of them play and how I choose to play it today.
