Susan,
Thanks for the Nora Cleary version. I'm sorry I can't agree with you though. No matter what it sounds like when sung the text looks like a refacimento due to the forgetting of some parts. The lack of rhyme in places would also point to this. What I would call a typical traveller version. Before anyone jumps in on this I am not running down traveller versions in any way. They can be and often are just as beautiful as any other version, often to me more beautiful because they have evolved further down the line. As to this being precedent to any of the other British versions, highly unlikely.
