Frankie Valli and the Four Seasons are an American pop band who, according to the Vocal Group Hall of Fame, were the most popular rock band prior to the Beatles, achieving international success by the 1960s. The original name of the group was the Four Seasons Partnership, formed by Valli and Bob Gaudio.
Frankie Valli and the Four Seasons released their first album in 1962. Their first charted hit, "Sherry," was also their first number one song. The success of "Sherry" lead to even greater milestones with follow-up singles "Big Girls Don't Cry" and "Walk Like a Man," which also reached number one chart spots.
Lead singer Frankie Valli, joined by tenor Bob Gaudio on keyboards and backing vocals, Tommy DeVito on lead guitar and baritone vocals, and Nick Massi on electric bass and bass vocals, formed the original line-up of the band. As of November 2015, Valli and Gaudio are the only members who have remained constant. However, Gaudio no longer performs live, leaving Valli as the only touring member.
