I've also heard the Bobbie Burns one called Green Grow The Rashes O'. Burns was Scottish, yet this song seems to be speaking of Ireland.
I know another version of Green Grow The Rushes Oh with words more like:
I'll sing you one O'...Green Grow The Rushes Oh
What is your one O' ....One is one and all alone and never more shall be so...Then I'll sing you 2 O' Green Grow The Rushes O', What is your 2 O', Two Two Lillie White Boys looking at the Wild World O'...One is one and all alone and never more shall be so. Then 3, 4, ete. I'm running out the door, and don't have time to right the rest, but that's the words. There are both versions sun on You Tube when you put in Green Grow The Rushes.
