Flower_Mary, вот что пишет Кристиан Нордейде, один из участников этой (и не только!) группы:
There are no tabs for this as far as I know. We sort of improvised this over a tune we called Brian Boru's Harp solo. Also known as "Port ui Mhuirgheasa" a fairly well known Irish jig. Our version was inspired by Alan Stivels recording on his "Renaissance de la harpe celtique" album from the 70's. Also in the mix we threw in some phrases from a Breton tune.

Так что это действительно вариации на тему )
