To Richard-I like your sense of humour..
Sorry about bursting the bubble of "airy -fairyness", but I do believe in fairies ,and have had a fascination with their existence since I was a child. In fact , I think they helped me write the song....
I also know many people who have heard the Bean si (banshee) cry , just before someone died, so I am not as "nuts and bolts " as you suggest...
"nuts " maybe...B.
