60 years ago today, on March 30, 1963, Lesley Gore recorded "It's My Party" at Bell Sound Studios in New York City. "We went into the studio at two o'clock in the afternoon, and came out at five o'clock, on budget, on time, with three songs cut and mixed." Rush-released three days later on April 2, "It's My Party" exploded onto the charts, and by June 1, the song was #1 on the Billboard Hot 100.
