Alan Stivell, “She Moved Through the Fair” (1973).
Stivell is a French harpist and singer. His version has beautifully simple music (harp and something drone-y in the background) and a slightly slurred vocal. He sings verses 1, 2 and 4 of the modern lyrics, following most of the common variations (i.e. “Mother/Father”, “Dead love” etc.).
You’ll also find Stivell on this live version with Jim Kerr (of Simple Minds) on the mic.
