Frankie Valli Net Worth: Frankie Valli is an American popular singer who has a net worth of $60 million. Frankie Valli gained his net worth by being the lead singer of The 4 Seasons and was indicted into the Rock and Roll Hall of Fame in 1990. Born Francesco Stephen Castelluccio on May 3, 1934, in Newark, New Jersey, US, he is most famous as frontman of The Four Seasons, especially in the mid 1960s. Valli's unusually powerful falsetto voice is the signature sound behind dozens of chart-topping hits by the New Jersey-based group. From 1962 through 1968, Valli along with his friends and band-mates Tommy De Vito and Nick Massi and teenage prodigy Bob Gaudio scored 29 Top 40 hits. They include danceable hit singles like Sherry (1962), Big Girls Don't Cry (1962), Walk Like a Man (1963), Rag Doll (1964) and Let's Hang On! (1965) among others. Later on, Valli established himself as a solo artist with the brassy Can't Take My Eyes Off of You, which reached #2 in 1967. Since, he has made a balance between his own music career and his work with the band. In the mid 1970s, he struck gold in the disco era with his top-charting songs like My Eyes Adored You (1974), as well as the theme to Grease (1978). His vast opus kept him in the public eye as a nostalgia in the 1990s and early 2000s. Eventually, a proper respect was paid to his life and accomplishments with Jersey Boys, a wildly popular and award-winning Broadway musical in 2005. This production just endorsed Valli's enduring contributions to popular music along with the singular brilliance of his unique voice. As one of the original members of The Four Seasons (together with DeVito, Massi and Gaudio), Valli got inducted into the Rock and Roll Hall of Fame in 1990 and the Vocal Group Hall of Fame in 1999.
