The Four Seasons Fan Club

The Four Seasons were formed in 1961 with Frankie Valli as the lead singer, Bob Gaudio on keyboards, Tommy DeVito on lead guitar and Nick Massi on bass guitar who was replaced in 1964 by Joe Long on bass guitar and back-up vocals. This became the "definative" Four Seasons concert line up: Valli, Gaudio, DeVito and Long. Frankie Valli of course later went onto a very successful solo career and still preforms many of the Four Seasons hits in concert today.
