Sandy, the Pig Pudding version of Fox, I've also heard as Carrion Crow, only the chorus goes:
"Hey fal-air-o, gilt in a garrow
He fal-air-o, gilt in a gay
Up jumps John, a-ringin' on his bell,
With me in come kitty come Ky-mo-Ray>"

Ain't the folk process wonderful when it comes to nonsense words?
blessings,
