In 1958, The Cookies performed with Ray Charles and Ann Fisher for the Cavalcade of Jazz concert produced by Leon Hefflin Sr., held at the Shrine Auditorium in Los Angeles, on August 3.

Sammy Davis Jr. was there to crown the winner of the Miss Cavalcade of Jazz beauty contest.

[2] After backing Charles and other Atlantic Records artists, McCrea and Hendricks helped form the Raelettes in 1958.

This trio had the greatest success as the Cookies: under their own name; as backing vocals for other artists, including Neil Sedaka's hit songs "Breaking Up Is Hard to Do", "The Dreamer" and "Bad Girl"; and recording demos for Aldon Music, under the direction of Carole King and Gerry Goffin.

[1] Earl-Jean McCrea left the group in 1965 after two solo singles, which included the first recording of the Goffin/King song, "I'm Into Something Good", made famous by Herman's Hermits.

Dorothy Jones died in Columbus, Ohio, from complications of Alzheimer's disease on December 25, 2010, at the age of 76.
