Carla Benson (born 1953) and Barbara Ingram (1947–1994) were first cousins, growing up together in Camden, New Jersey, with their friend Evette Benton (1952–2021).
She auditioned successfully for Bell, who asked her to form a vocal trio to work as backing singers on studio recordings.
Bell and Huff immediately agreed to record them on a session by Joe Simon, and they rapidly became established as the label's in-house backing vocalists.
Among the artists with whom they recorded were Billy Paul, McFadden & Whitehead, The O'Jays, The Stylistics, Harold Melvin and the Bluenotes, Teddy Pendergrass, Lou Rawls, Elton John, and Dionne Warwick.
[1] Barbara Ingram and Evette Benton had several memorable guest appearances on hit songs; Ingram provided the sensual moans for the Major Harris classic, "Love Won't Let Me Wait," and played Teddy Pendergrass' love interest on "Come Go With Me," while Benton provided the mysterious, sultry female vocal on The Spinners' classic, "Games People Play."
