There are multiple versions of the words; sometimes you can even identify the area where the song was collected by the form the lyric takes.
I remember the original publication of this traditional ballad (in a small press magazine). Quite a few years later, I got to know its author fairly well - and heard the sem-legendary story of how you write a folksong.
As soon as he realised that William Price was being reported as a traditional folksong, the author carefully removed as many traces that linked him to it as he was able. He has published a
Collected Poems - there is no trace of "William Price" in it.
You would need to be at least my age to be aware of the real backstory to the words (it would help to be quite a bit older); so in a generation or so, 'William Price' will have become a true folksong.
