Jersey Boys is the story of Frankie Valli and The Four Seasons: Frankie Valli, Bob Gaudio, Tommy DeVito and Nick Massi. This is the story of how a group of blue-collar boys from the wrong side of the tracks became one of the biggest American pop music sensations of all time. They wrote their own songs, invented their own sounds and sold 175 million records worldwide - all before they were thirty.
