Ewan MacColl and Peggy Seeger did five versions on The Long Harvest LP set. It's from volume 6, 1967, but they had been singing at least two of the versions since the 1950s at least. I'll give you the opening stanza of each, and maybe you can identify it:

1) O! False Sir John A Wooin Came
To a maid of beauty rare
May Colvin was this lady's name
Her Father's Only Heir

2)It's of a handsome tall young man
William was his name
He come across the raging sea
all for the courting of me, of me,
all for the courting of me

3) An outlandish knight from the north lands came
and he came wooing to me
He promised he'd take me to the north lands
and there he'd marry me

4)Billy came over the main white ocean
Billy Came over the sea
Billy Came down to my father's house
Billy came courtin' of me, of me
Billy came courtin' of me

5) There was a youth, a cruel youth
he lived beside the sea
six pretty maidens he drowned there
by a lonely willow tree.

Anything ringing a bell?
