Lidi / Laoise"She moved through the fair" - one of my favourite songs of all time, especially in the Margaret Barry recording.
I play it myself, with guitar based on (I think it was) Davie Graham's version. I also sing it, but only when I'm by myself 'cause it's so difficult (or I'm a bad singer which is more likely).
Just in case Lidi hasn't got the words, they are available in the Digital Tradition archive.
Cheers
Rick.
