The group comprised Patricia Bennett, Judy Craig, Barbara Lee and Sylvia Peterson. The group had already recorded a handful of singles when they hit the number one spot in the United States with the song "He's So Fine" (the distinctive riff later appearing in George Harrison's "My Sweet Lord", prompting a copyright infringement claim).
Their first hit was followed by other notable tunes such as Goffin-King's "One Fine Day", "Sweet Talkin' Guy" and "I Have a Boyfriend", although many of their recordings were derivative of the period. The group also released material under the title The Four Pennies.
The Chiffons disbanded in 1972.
