Hard to find

I had first heard this song while watching The Abyss, One Knight, the lady driving the tow rig popped it into a tape player and the entire crew started singing it, couple days later i was humming the damn thing and had to find it, turns out (as far as i'm concerned) this is one of the greatest songs ever made. 15 years later, i'm still not sick of it.. and it's been around since the early 70's.
