Looking for a particular cover of "Everlasting Love"

[_B4U_]

There used to be a "what's that song..." sticky here, but guess that died. Anyway, my friend claims to have heard a version of "Everlasting Love" that was sung by a man/woman duet from somewhere between the 70's and 90's. She said it's not Rex Smith & Rachel Sweet, so I'm not sure who it would have been since I don't see any other duets on Wikipedia... If any of you know who the singers may have been, can you let me know? Thanks a ton!
