The Four Seasons (band)

The Four Seasons is an American rock and pop band that became internationally successful in the 1960s and 1970s. 
Since 1970, they have also been known at times as Frankie Valli and the Four Seasons. In 1960, the band known as the Four Lovers evolved into the Four Seasons, with Frankie Valli as the lead singer, songwriter Bob Gaudio (formerly of the Royal Teens) on keyboards and tenor vocals, Tommy DeVito on lead guitar and baritone vocals, and Nick Massi on electric bass and bass vocals.
The Four Seasons were one of only two American bands (the other being the Beach Boys) to enjoy major chart success before, during, and after the British Invasion.
