AS Jon W. said, there was also a group named Planxty. I believe it was where Christy Moore started out. From what I've heard Planxty was sort of at the lead of the revival of traditional Irish music during the 70's. In his song Lisdoonvarna, Christy Moore refers to several different singers and bands including "Moving Hearts, and Planxty too"...both are bands of which he was a member. This is probably not at all what you were asking about...but I really really wanted to join a discussion.
