Little Sister was an American all-female vocal harmony group, which served primarily as the background vocalists for the influential rock/funk band Sly & The Family Stone in concert and on record. Originally a gospel music group called The Heavenly Tones, Little Sister was composed of Vet Stewart (Family Stone frontman Sly Stone's "little sister"), Mary McCreary, and Elva Mouton, and became a recording act of its own for a brief period in 1970-1971.
