The Four Seasons (since 1967, known off and on as Frankie Valli and The Four Seasons - although not shown that way on any of their hit records), is an American pop and rock group. They also had a sound somewhat reminiscent of doo-wop, although they were not thought of as a doo wop quartet. By the mid 1960s, The Four Seasons had become an internationally famous rock and roll group. In 1960, the group known as The Four Lovers evolved into The Four Seasons, with Frankie Valli as the lead singer, Bob Gaudio (formerly of The Royal Teens) on keyboards and tenor vocals, Tommy DeVito on lead guitar and baritone vocals and Nick Massi on bass guitar and bass vocals (Massi was replaced in 1965 by Charles Calello, who was in turn replaced later in 1965 by Joe Long on bass guitar and bass vocals).
In 1962, the group released their first album featuring the single "Sherry", which was not only their first charted hit but also their first number one song. Under the guidance of producer/songwriter Bob Crewe, The Four Seasons followed up "Sherry" with several million-selling hits, including "Big Girls Don't Cry" (their second #1 hit), "Walk Like a Man" (their third #1), "Candy Girl", "Ain't That a Shame", and several others. In addition, they released a Christmas album in December 1962 and charted with a unique rendition of "Santa Claus Is Coming to Town". [wikipedia]
