I wonder if Nic has been rather naive when it came to copyrighting arrangements;
After all, as we have heard, Nic took lines from a number of versions, and then put it all together with an "adapted" tune.
And that is the version that "everyone" on Youtube sings.

But, like Tunesmith, the thing that annoys me is that the praise and the attention that Nic deserves is being lavished on Loreena Mckennit and Mary Black.

PUT UP NIC'S VERSION!
