After their lack of success under contract to Colpix Records between 1961 and 1963, the Ronettes ended their Colpix contract and signed with Phil Spector's Philles Records in early 1963. During their first few months with Phil Spector, the Ronettes achieved mainstream success with the release of "Be My Baby" in August 1963, which climbed to number two on the US "Billboard" Hot 100 and peaked at number one on the "Cashbox" Hot 100. It was the success of "Be My Baby" which had Spector eager to do a follow-up for the Ronettes in the fall of 1963.
