Coming very late to this party: I discovered recently that this song is the same as a Dixieland number, "Mama's Gone, Good Bye," published by Clarence Williams in 1924 and credited to Peter Bocage and A.J. Piron. I am trying to track down whether Sippie covered the song and somehow Muldaur did not know the origin and credited Sippie, or whether it's Sippie's tune and Bocage/Piron merely took the credit. Williams is the place where this gets murky, because he frequently collaborated with Sippie. If anyone knows more, I would love to hear from you!
