Frankie Valli, whose real name is Francesco Stephen Castelluccio, was born on May 3, 1934 in Newark, New Jersey to an Italian American family. His father was a barber named Anthony Castelluccio and his mother, Mary Rinaldi, worked for a beer brewing company. Valli was inspired to become a singer after his mother took him to see a Frank Sinatra concert in New York City when he was 7 years old.
Before he became famous as a vocalist, Frankie Valli worked as a barber. At a young age, he decided to change his last name to "Valli" in honor of his musical mentor, "Texas" Jean Valley.
His first musical group, the Variety Trio, formed in 1951. When they disbanded the following year, Valli joined another group called The Four Lovers, which eventually became The Four Seasons in 1961 after several lineup changes. The Four Seasons became a successful pop group in the 1960s, beginning with their 1962 hit "Sherry," which ended up at No. 1 on the Billboard pop and R&B charts.
In addition to his long musical career, Valli has also appeared on several television programs, including "Miami Vice" and "The Sopranos." The Broadway musical "Jersey Boys," first performed in 2005, tells the story of Frankie Valli and the Four Seasons.
