File - In this May 2, 2008, file photo, singer Frankie Valli performs at the 15th annual Race to Erase event in Los Angeles. A federal appeals court has revived a copyright lawsuit against Frankie Valli and fellow "Four Seasons" band member Robert Gaudio over "Jersey Boys," the popular musical about the band. Donna Corbello sued Valli and Gaudio in 2011 for copyright infringement, claiming the musical was based in part on an unpublished autobiography of "Four Seasons" band member Thomas DeVito that her late husband ghost-wrote.
