The group was originally a trio of schoolmates - lead singer Judy Craig, backed by Patricia Bennett and Barbara Lee - enrolled at James Monroe High School in the Bronx in 1960.

This first hit was followed by other notable tunes such as Gerry Goffin and Carole King's "One Fine Day", "Sweet Talkin' Guy" and "I Have A Boyfriend".

To promote the record, Sylvia and Barbara flew to the West Coast to premiere the disc on a July 1965 Shindig episode, with two substitute members as Judy and Pat were on maternity leave.

Laurie released several minor US chart hits on the Chiffons (including “Up On The Bridge”, “My Boyfriend’s Back)” until the end of the 60s.

Tiring of the constant touring and lack of hits, Judy Craig left the group in 1972, and she took a bank job in Manhattan.

Eventually, Sylvia, Pat, and Barbara took on regular 9-5 jobs, but continued to do live shows on weekends.

In 1970, George Harrison released the song "My Sweet Lord", whose musical similarities to "He's So Fine" prompted the estate of Ronnie Mack to file a copyright infringement claim.
