An Alarc'h is 'close' to the tune Jean Redpath uses, though she starts the 3rd line similar to 1 & 2, then moves to the higher note and decends on 'the other did say'...(very small differences in tune and wording can change the character of this song a lot)

As I was walking all alane
I heard twa corbies makin' mane
And one ontae the other did say
Where will we gang and dine the day
Where will we gang and dine the day
