I am really glad you started this thread. Somewhere, on a long lost tape I remember a song about Oisin and Niamh and the Isle of Tir Na n-Og. I am pulling from memory, so forgive mistakes but it seems like it started with

Across the misty morning Isle of Erin,
Comes Niamh ......on her snow white steed

Anyone remember this? I would love to figure out who did it and get a CD. Damn, one part of aging that sucks is when the memory starts to go......
