The original members were Jennifer McQuilkin of New Jersey, Daphne Rubin-Vega of Panama, and Suzi Ranta of Michigan with songwriter Peggy Sendars and songwriter/producer Jim Klein.
The band's biggest hit single, "Yo No Sé" (1988) (sung by Jennifer McQuilkin), was one of the first freestyle songs in which the title was entirely in the Spanish language, which peaked at #75 on the Billboard Hot 100 chart.
The next single, "Hide and Seek" (1990) (remixed by Robert Clivillés and David Cole) became their first music video.
The singles charted on the Billboard Hot Dance Club Songs, and the group toured with New Kids on The Block, George Lamond, Sweet Sensation, Brenda K. Starr, Linear, and Sa-Fire.
In 2000, for a celebration held in honor of Fever Records's Sal Abbatiello, a new version of Pajama Party graced the stage.
