"It's My Party" was released on April 5, 1963, as the lead single from Lesley Gore's debut album I'll Cry If I Want To (1963). Lyrically it portrays the discomfort of a teenage girl at her birthday party when her boyfriend Johnny disappears, only to return in the company of Judy, another girl, who is "wearing his ring", to indicate he has replaced the birthday girl as his love interest. The song's effectiveness is enhanced by several musical touches that producer Quincy Jones incorporated, including Latin-sounding rhythms, double tracked vocals, and effective horn parts. "It's My Party" reached the number one position in the United States, Canada, Australia, and New Zealand.
