11:05 Marty Duda's artist of the week: The Four Seasons

Led by the piercing vocals of Frankie Valli, The Four Seasons became one of the biggest musical acts of the 1960s. Although they began as a doo-wop group in New Jersey, they were one of the few groups to continue to be successful before and after the 1964 British invasion. They finally ran out of steam at the end of the sixties, but experienced a second wave of fame in the mid-70s with disco-pop tunes like Who Loves You and December, 1963 (Oh, What A Night). Valli had a parallel solo career and many of his hits were actually Four Seasons tracks. The group has had a resurgence of interest lately thanks to the musical play and subsequent film of Jersey Boys. Long-time songwriter and producer Bob Crewe passed away over the weekend. Frank Valli still leads a group of Four Seasons at the age of 80.
