Problem: Background: The Ronettes () were an American girl group from New York City. One of the most popular groups from the 1960s, they placed nine songs on the Billboard Hot 100, five of which became Top 40 hits. The trio from Spanish Harlem, New York, consisted of lead singer Veronica Bennett (later known as Ronnie Spector), her older sister Estelle Bennett, and their cousin Nedra Talley. Among the Ronettes' most famous songs are "Be My Baby",
Context: After their night at the Apollo, Ira, Elaine, and Diane left the group. After the curious renaming of the group to "Ronnie and the Relatives", Ronnie, Estelle, and Nedra began taking singing lessons two afternoons per week. Appearing at local bar mitzvahs and sock hops, they met Phil Halikus, who introduced them to Colpix Records producer Stu Phillips. According to Ronnie, Phillips played the piano while the women auditioned for him, singing "What's So Sweet About Sweet Sixteen". The audition was successful, and the group was brought into the studio in June 1961 and recorded four tracks: "I Want a Boy", "What's So Sweet About Sweet Sixteen", "I'm Gonna Quit While I'm Ahead", and "My Guiding Angel". Colpix released "I Want a Boy" in August 1961 and "I'm Gonna Quit While I'm Ahead" in January 1962, the first singles credited to Ronnie and the Relatives.  While both singles failed to chart on the Billboard Top 100, fate intervened in advancing the group's success. A fortuitous case of mistaken identity led to Ronnie and the Relatives making their debut - as dancers rather than a singing act - at New York City's hip The Peppermint Lounge in 1961. It was the height of the Twist craze, and under-aged Nedra and Ronnie disguised themselves to get in. The girls' mothers showed them how to put on make-up and fix their hair to make them look at least 23. When they arrived outside the club, its manager mistook Ronnie, Estelle, and Nedra for the trio supposed to dance behind house band Joey Dee and the Starliters for the evening. He led them in and put them onstage to perform in their place. During the show, Starliter David Brigati even handed the mic over to Ronnie when she started to sing Ray Charles' "What'd I Say". Soon afterward, Ronnie and the Relatives became a permanent act at The Peppermint Lounge, each earning $10 per night to dance The Twist and usually sing a song at some point in the show.  Ronnie and the Relatives soon became "The Ronettes". Colpix issued the first two singles credited to the Ronettes, "Silhouettes" and a re-issue of "I'm Gonna Quit While I'm Ahead", on its May label in April and June 1962, respectively. Both singles disappointingly failed to chart. Later that year, they were flown to Miami to open a Florida branch of The Peppermint Lounge. After their performance at the Miami gala, radio host Murray the K came backstage and introduced himself to them. He asked the women to begin appearing at his shows at The Brooklyn Fox in New York. They agreed, taking the Fox stage in 1962 and completing a transition from Murray the K's "Dancing Girls", to back-up singing for other acts, to performing as the Ronettes before year's end. It was during this time that the women evolved their iconic look, wearing ever more exaggerated eye make-up while teasing their hair to impossible proportions. "We'd look pretty wild by the time we got out onstage," Ronnie later recalled, "and the kids loved it." Colpix's May label issued a final single by the Ronettes in March 1963. When "Good Girls" failed to chart, the women decided to look elsewhere for studio work.
