While the name Jean Knight may not ring a familiar bell, the song "Mr. Big Stuff" surely does -- or should -- with it's poppin' 1970s Funk groove curled beneath Knight's sassy vocals and lyrics that make "You're So Vain" seem like a loving ode by comparison. Knight may not have produced another hit in the Disco or Reagan eras, but the song was enough to keep her memory alive on Soul stations and, in a slightly altered form, in Oreo commercials.
