[1] In 1960, at age 15, she was invited to sing in the girl group the Crystals.

[1] Although she rarely sang lead on their songs (her voice was, according to her bandmate, Barbara Alston, "too high and soft"), she was the only member who stayed in the group from their formation to their disbanding.

With the Crystals, she enjoyed a successful (but not very long) career in music.

In 1971, Kenniebrew and her former bandmates (Dolores "LaLa" Brooks, Mary Thomas, and Barbara Alston) reunited to tour and perform on the oldies circuit.

According to Kenniebrew's Facebook page, in 2005 she and original Crystals Alston and Brooks performed together at the Vocal Group Hall of Fame, where girl-group postage stamps were unveiled.
