Not the cast from Jersey Boys. Not a Jersey Boys tribute show. Not a Frankie Valli and The Four Seasons cover band. The real members of this amazing supergroup of musicians, vocalists, arrangers and composers actually were the Four Seasons who sang with Frankie Valli. They were the Shondells who sang with Tommy James. They are the authentic rock and rollers whose legacy includes hundreds of hit records from the 60s, 70s and 80s.
