Was it live or a studio recording? The studio recording is a B-side of the Japanese Livin in Sin-Single. Live could either be from an American TV show from some time in the 80s or from Yokohama. But in Yokohama they sang it different than on the CD-single. The CD-single is more a duet than lead- and backing vocals. In Yokohama it was lead- and backing vocals as all other songs.

The version on the Single-CD is my all time fav acoustic version of a BJ-song. I absolutely love it.
