The Four Seasons is an American rock and roll and doo-wop band formed in 1960 in Newark, New Jersey. Since 1970, they have also been known at times as Frankie Valli and the Four Seasons. The band evolved out of a previous band called The Four Lovers, with Frankie Valli as the lead singer, Bob Gaudio on keyboards and tenor vocals, Tommy DeVito on lead guitar and baritone vocals, and Nick Massi on bass guitar and bass vocals. On nearly all of their 1960s hits, they were credited as The 4 Seasons. The legal name of the organization is the Four Seasons Partnership, formed by Gaudio and Valli, and was taken after a failed audition in 1960. While band members have come and gone, Gaudio and Valli remain the band's constants, with each owning 50% of the act and its assets, including virtually all of its recording catalog. Gaudio no longer plays live, leaving Valli as the only original member of the band who still tours as of 2022. The band's original line-up was inducted into the Rock and Roll Hall of Fame in 1990, and joined the Vocal Group Hall of Fame in 1999. They are one of the best-selling musical groups of all time, having sold an estimated 100 million records worldwide.
