Reading up on Grover Washington Jr.'s 1980 album "Winelight," it seems one track "In the Name of Love" was later re-released, with Grover's saxophone wiped off and vocals overdubbed instead by Bill Withers, and it was released as a Ralph MacDonald/Bill Withers song.
Has this ever happened before? Backing tracks re-used for more than one release? I can't recall any.
