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",
In early 1963, fed up with Colpix Records and the group's lack of success, sister Estelle placed a phone call to producer Phil Spector and told him the Ronettes would like to audition for him. Spector agreed and met the women soon after at Mira Sound Studios in New York City. Later, Spector told Ronnie that he had seen them at The Brooklyn Fox several times and was impressed with their performances. At the audition, Spector was sitting at a piano, and when the group began singing "Why Do Fools Fall in Love", he suddenly jumped up from his seat and shouted: "That's it! That's it! That's the voice I've been looking for!" After their successful audition, Spector decided to sign the group. Originally, he wanted to sign Ronnie as a solo act, until her mother told him either he signed the Ronettes as a group or it was no deal. He agreed to sign the group and instructed Ronnie's mother to inform Colpix Records that the women had "given up" on show business so the studio would release their contract. By March 1963, the group was officially signed to Spector's Philles Records. The first song the Ronettes rehearsed and recorded with Phil Spector was written by Spector, Jeff Barry, and Ellie Greenwich called "Why Don't They Let Us Fall in Love". They brought the women out to California to make the record, but, once it was completed, Spector declined to release it. They recorded more songs for Spector, including covers of "The Twist", "The Wah Watusi" (lead vocals by Nedra), "Mashed Potato Time", and "Hot Pastrami". These four songs were released, but were credited to The Crystals on their 1963 Philles LP The Crystals Sing Their Greatest Hits, Volume 1.

Why did they leave Colpix Records ?

Allan Robert Border AO (born 27 July 1955) is a retired Australian cricketer. A batsman, Border was for many years the captain of the Australian team. His playing nickname was "A.B.". He played 156 Test matches in his career, a record until it was passed by fellow Australian Steve Waugh.
In 1981, Border made his first Ashes tour and scored a half-century in each of the first two Tests. "Border alone of the established players came through with reputation enhanced"; in the Fifth Test at Old Trafford when he batted with a fractured left finger. He reached a century in 377 minutes, the slowest Test hundred by an Australian, and remained unbeaten on 123 as Australia lost the match. In the final Test at The Oval, Border scored 106 not out and 84. During this latter sequence, he defied the English bowlers for more than 15 hours to score 313 runs before he was dismissed. Overall, he totalled 533 (at 59.22); this prompted Sir Leonard Hutton to call him the best left-handed batsman in the world and resulted in his selection as one of the Wisden Cricketers of the Year in 1982. Border's 1981-82 season was mixed. Against Pakistan, he made only 84 runs in three Tests, but against the West Indies, he scored a century and three half-centuries in 336 runs (at 67.20) to help Australia draw the series. On the tour of New Zealand, his three Tests brought only 44 runs at 14.67. After having the winter off, Border returned to Pakistan but was unable to repeat his performances of two years earlier. He scored 118 runs at 23.60 as Pakistan won all three Tests. After failing in the first three Tests of the 1982-83 Ashes series, Border's place in the Australian team was in jeopardy as Australia led the series 2-0. Border's effort in Australia's loss in the Fourth Test at the MCG is one of his best remembered Test innings. Australia had lost nine wickets and required 74 runs to win when Jeff Thomson joined Border at the crease. 18,000 spectators attended the final day's play as the pair slowly accumulated runs, before a juggling catch dismissed Thomson three runs short of the target. Border then scored pair of 80s in the Fifth Test to secure a drawn match and Australia regained the Ashes. His figures were 317 runs at 45.28 average.

What performances did he do 2 year earlier?

Border's 1981-82 season was mixed. Against Pakistan, he made only 84 runs in three Tests,

Gregory Allen Kurstin (born May 14, 1969) is an American record producer, musician and songwriter. Described as "the consummate DIY writer and producer", Kurstin has been associated with releases which have cumulatively sold more than 60 million albums worldwide. He has won five Grammy Awards, including Producer of the Year (Non-Classical) in 2017 and 2018. Kurstin co-wrote, produced and played most of the instruments on the record-breaking 2015 Adele single, "Hello".
In 2004, Kurstin was introduced to singer Inara George by a mutual friend, Mike Andrews. Then producing George's solo debut, Andrews hired Kurstin as a pianist for the album. Kurstin and George clicked musically in the studio and together they formed The Bird and the Bee (stylized as "the bird and the bee"). Shortly thereafter, they were signed by Blue Note Records chairman Bruce Lundvall. Described by Entertainment Weekly as "space-age pop that cunningly combines bossa nova languidity with Beach Boys-style lushness", they have since released four albums and an EP. Kurstin was nominated for a Grammy Award for Best Engineered Album for the Bird and the Bee's 2015 release, Recreational Love. After working on tracks with artists including Peaches, All Saints, Pink, the Flaming Lips, and Kylie Minogue, Kurstin was introduced to Lily Allen. Along with other musicians, co-writers, producers and engineers, he worked on her 2006 debut, Alright, Still, which went on to achieve platinum status. For her second album It's Not Me, It's You, Allen worked exclusively with Kurstin; he co-wrote every song and played all of the instruments on the record, which he also engineered and produced. The album's first single, "The Fear", spent four weeks at number 1 in the UK, and the album hit number 5 in the US and charted in the top 10 in eight other countries. With Allen, Kurstin won three Ivor Novello Awards for his work on the double-platinum It's Not Me, It's You. Based in part on the album's success, as well as his work on a bird and the bee record, Kurstin was nominated for his first Producer of the Year Grammy in 2010. Kurstin's first commercially available collaboration with Sia was "Death by Chocolate", released on her 2008 album Some People Have Real Problems. In 2010, he produced Sia's fifth album, We Are Born. It reached number 2 in Australia and number 37 in the US. It won ARIA Music Awards for Best Pop Album and Best Independent Release.
