There is a song Dervish recorded on their "Live in Palma" CD and I don't even know what it is called. Cathy sang it unaccompanied on the CD. I assume that Lough Erin's Shore is the name. I wish you could hear me humming the tune. Does anyone know where this song is from? Anyone have the full lyrics?
