(The Best Part of) Breakin' Up
However, according to Ronnie Spector, the group's lead singer, producer Phil Spector had already begun to somewhat lose enthusiasm for the Ronettes in early 1964. The group had recorded the Phil Spector, Jeff Barry, and Ellie Greenwich song "Chapel of Love" in early 1964, but Spector refused to release it. "It doesn't sound like a hit," he told the group, so The Dixie Cups recorded their version of the song, which peaked at number one on the Billboard top 100, a position never held by the Ronettes.

The Ronettes were a popular live attraction around the greater New York area in the early 1960s. Looking for a recording contract, they initially were signed to Colpix Records and produced by Stu Phillips. 
After releasing a few singles on Colpix without success, they were signed by Phil Spector to Philles Records. Their relationship with Spector brought chart success with "Be My Baby", "Baby, I Love You", "The Best Part of Breakin' Up", "Do I Love You?", and "Walking in the Rain". The group had two top 100 hits in 1965: "Born to Be Together" and "Is This What I Get for Loving You?" The group broke up in early 1967, following a European concert tour that included their appearance at the Moonlight Lounge, in Gelnhausen, Germany, where they entertained American military personnel. The Ronettes were never to reunite until their 2007 induction into the Rock and Roll Hall of Fame.
