The story of how an underachieving bunch of singers from the mean streets of New Jersey rose from several years in obscurity to international stardom. The centrepiece of the tale is the extraordinary relationship between lead singer Frankie Valli and the writer of many of their classics, Bob Gaudio, which began in the late 1950s and continues to this day. Presented by Paul Sexton. 3/4. By the end of 1967, dusk was falling on the Four Seasons' incredible heyday of American hits, as pressures continued to pull the group apart. But the band also began to go creatively in new directions.
