A folk band from Maine, Northeast Winds, had a song called "A Song of Exile" and it had all of the aforementioned Marion Zimmer Bradley lyrics and a third verse (the chorus was "We sing in this far land...")

I'm not sure who wrote them but here they are...

Oh when will my heart e’er be free of this longing?
When will I finally find peace of mind?
When waking and sleeping the past comes to haunt me
And ties that once strengthened are chains now that bind

Then they repeated the "chorus" - We sing in this far land...

The recording was on an album titles "Easy and Free". I can't for the life of me track it down. My mom had the cassette. I've recently reached out to two of the members of the, now extinct, band, via Facebook.

The saga continues...
