The DT version with music from Canada, it begins:
As I walked over London bridge
Oh so early in the morning,
It was there I met a pretty fair maid
All lamenting for her Geordie.
What has he done? Who has he killed?
Has he murdered anybody?"
"No, he stole five pearls from the royal king
And he sold them in a hurry."
Attributed to Folk Songs of Canada, Fowkes. I have the 1954 book and Geordie is not in there. Where is it from? Who was the informant?
