They formed in the late 1950s in junior high school and consisted of Hightower, Davis, and three Brickley sisters: Shirley, Jean, and Audrey.
A high school friend, Dovells lead singer Len Barry, encouraged them to audition for Cameo-Parkway Records at the turn of the decade.
Cameo executive Dave Appell appointed Hightower as the lead singer, and began writing songs for them.
A short-lived stint by Yvonne Young was followed by original Teenette, Audrey Brickley, Shirley's sister.
[1] Hightower had a successful career as a soloist and as an in-demand session singer, backing Joe Cocker, John Holt and other artists.
In later years, Davis married and found work as an executive secretary, whilst Caldwell became a shop steward of the bus drivers' trade union, and then became the administrator of the union's legal fund in Philadelphia and served on the Philadelphia Board of Education for 29 years.
In March 2012, Caldwell and Brickley took part in the benefit single "Mull of Kintyre", featuring Charlie Gracie with Clutch Cargo.
"The Wah-Watusi," "Don't Hang Up," and "South Street" each sold over one million copies and were awarded gold disc status.
