Here's the chorus of Barbagal:

E foli, fola, follero, e follero, lero, li
O bun om Barbagal pour'om
Diridin don, diridon, poura mi.

And here's the chorus from the version of Daddy Fox by Sylvia Herold (same exact tune):

E foli fola folero
E folero lero li
Up jumped John, ringing on his bell
With a ding dong dilly dong cora mi.

To muddy the waters even more, here are the liner notes from "In Harmony's Way":

"Sylvia's version of this well-known song came from a group of four young British folk songstresses called The Witches of Elswick. They tell us that the words were pu to the tune of 'The Carrion Crow' by Mick Peat, who produces a folk music radio show in England."

Who's on first?
