Ronnie Spector
Ronnie Spector (born Veronica Yvette Bennett; August 10, 1943) is an American rock and roll singer known as "The Bad Girl of Rock & Roll". Spector was the lead singer of the rock/pop vocal girl group the Ronettes, who had a string of hits during the early to mid–1960s such as "Be My Baby", "Baby, I Love You", and "The Best Part of Breakin' Up". Subsequently, Spector launched her solo career and has since released five studio albums ("Siren" in 1980, "Unfinished Business" in 1987, "Something's Gonna Happen" in 2003, "Last of the Rock Stars" in 2006, and "English Heart" in 2016) and one extended play ("She Talks to Rainbows" in 1999).
Gladys Horton
Formerly calling themselves "The Casinyets (can't sing yet)", the group eventually auditioned for Motown after a talent contest, and while the audition was successful, the group was requested to return to Hitsville with an original song. After member Georgia Dobbins co-created the song "Please Mr. Postman", Dobbins suddenly left the group after her father forbade her to be in nightclubs. Dobbins, who was also the group's original lead singer, gave Horton the spotlight to be the lead vocalist, a spot Horton was not comfortable with in the beginning. The group changed their name to the Marvelettes shortly after Motown signed the act and released "Please Mr. Postman" in the summer of 1961 when Horton was reportedly just fifteen years old.
