Here is Marcella Detroit (Marcy Levy) with her take on "Lay Down Sally" (Eric Clapton - Marcy Levy - George Terry). Mary sang backup with Detroit's Bob Seger.

Eric Clapton's "Lay Down Sally" peaked at number three on Billboard and is from the 1977 top ten album "Slowhand". Marcella is on backing vocals along with Yvonne Elliman. The single made a showing on both the Country and Adult Contemporary charts too.
