"It's My Party" is a song most famously sung by American singer Lesley Gore in 1963. This song hit #1 on the pop and rhythm and blues charts in the United States. . "It's My Party", peaked at #9 in the United Kingdom, becoming Gore's only major hit there. It was the first hit single for producer Quincy Jones.

The song lyrically portrays the discomfiture of a teenage girl at her birthday party when her boyfriend disappears only to surface in the company of another girl who's "wearing his ring" to indicate she's replaced the birthday girl as his love interest.

The song's chorus, "It's my party, and I'll cry if I want to... You would cry too if it happened to you," became a part of American pop cultural language as a phrase used to describe being utterly humiliated and miserable during an event that is supposed to be a happy occasion.

"It's My Party" was written in 1962 by John Gluck, Wally Gold and Herb Weiner who were staff writers employed at the Aaron Schroeder Music firm. The demo for the song was cut by Barbara Jean English a girl group veteran (the Clickettes, the Fashions) who was then working as both a receptionist at the firm and, with Jimmy Radcliffe, serving as its in-house demo singer; Radcliffe produced the demo and according to English "tried to persuade Musicor [the label owned by Aaron Schroeder] to release it as a record, or to take me into a master studio and redo it, but they weren't interested."[1]

The first recording of the song was by Helen Shapiro for her Helen in Nashvillealbum recorded in February of 1963 with Shapiro's regular producer Norrie Paramor and also Al Kasha. Shapiro would recall: "Right from the first time we heard the song on the rough demo back in London, we thought we were going to sock them between the eyes with that one";[2] however Shapiro's version was not one of the cuts chosen as an advance single from the album and by the time of the album's release that October the "It's My Party" track was perceived as a cover of Lesley Gore's hit.

Lesley Gore recalls that "It's My Party" was among some two hundred demos producer Quincy Jones brought to review with her in the den of her family home in February of 1963. On hearing "It's My Party" Gore told Jones: "That's not half bad. I like it. Good melody. Let's put it on the maybe pile." The song proved to be the only demo Gore and Jones found agreeable. With Jones producing and Claus Ogerman handling arranging and conducting duties, Gore recorded "It's My Party" at Bell Sound Studios in Manhattan on 30 March 1963.[3]

In March of 1963 that Phil Spector heard the demo of "It's My Party" while visiting Aaron Schroeder's office. Wally Gold would recall: "He [Spector] said, 'Great, I love it. I’m gonna do it with the Crystals.' We [the song's writers] were really excited, because that would ensure that the record was #l!"[4]

Schroeder apparently only learned of the Lesley Gore recording of "It's My Party" when Quincy Jones invited him to hear the completed track, which Schroeder found formulaic; believing that Spector would be able to cut a much stronger version of the song with the Crystals and not wanting to lose Spector's goodwill, Schroeder attempted to convince Jones to suppress the track. Schroeder didn't mention Spector's version to Jones but Jones and Spector both happened to attend a concert at Carnegie Hall on the evening of 30 March 1963 and when they met outside it came up in conversation that Spector had recorded a version of "It's My Party" with the Crystals. Jones skipped the concert instead spending that night - a Saturday - at Bell Sound Studios making a test pressing of the track comprising one hundred copies which over the next two days Jones mailed out to radio programmers in key markets across the US. Gore heard her record played on the radio for the first time that Friday; the official release of "It's My Party" came later in the month with the disc ascending to #1 nationally in four weeks.[5] [6] Jones was abroad at the time of "It's My Party"'s release; on his return he expressed dismay when Aaron Schroeder advised him that the rush release of "It's My Party" had precluded coining a more pleasant name for the singer than "Lesley Gore" to which Schroeder replied: "Didn't anybody tell you?...Quince, the record's number one. Do you really give a damn what her last name is?"

"It's My Party" has also been recorded by the Chiffons, the Paris Sisters, Brenda Lee, Sue Thompson and Carol Welsman.

In 1988 Chaka Khan reached #5 on Billboard's Black Music charts with a track entitled "It's My Party" which is not a remake of the Lesley Gore hit but rather a composition by Cecil and Linda Womack which describes a similar scenario to that in the Gore hit, but with the party's host reacting more aggressively.

Because of the pop cultural obsession with the song and the tragic nature of the song, Lesley Gore recorded a sequel titled "Judy's Turn to Cry". In the song, the teenage girl narrator gets her revenge on Judy after all the pain and humiliation she caused her. In the lyrics the narrator explicitly finds "foolish" how much she cried when she saw Johnny and Judy together, and seems determined to start anew. She kisses another guy in front of Johnny and Judy during another party, which causes a jealous Johnny to jump at and punch the other boy, then get back together with her.

"Judy's Turn To Cry" was not quite as popular as "It's My Party", but still was a sizeable hit, reaching #5 on the Billboard charts in the summer of 1963.
