Thanks Chris.
I'll have a bash at it tomorrow.
Saw Martin Simpson do it the other month and for a change I was listening to the words and not taking much notice of the music. Didn't even know what it was called until I accidently came across Nics' version. I haven't stopped listening to it since. Just love open tunings. Big fan of John Martyn but alas very hard to decipher. (As are most things for me)
Thanks again
