Bob Gaudio is an American singer/songwriter with a net worth of $15 million. Bob Gaudio also gained his net worth as a recorder producer and keyboard/backing vocalist for The Four Seasons. Gaudio was responsible for the group's string of hits, which included Sherry, Big Girls Don't Cry, Walk like a Man, Bye, Bye Baby and I Can't Take My Eyes Off You. During his lifelong career, he produced and co-wrote megahits for heavyweights like Frank Sinatra, Diana Ross, Michael Jackson, Barry Manilow, Eric Clapton and Roberta Flack. Before forming The Four Seasons, Gaudio came to fame as a member of the 50s act Royal Teen, co-writing the band's hit Short, Shorts. He met The Four Season frontman Frankie Valli and shortly after, he left Royal Teens, joining The Four Season a year later. Although Gaudio enjoyed considerable success with Four Seasons during the 60's, the 1969 album The Genuine Imitation Life Gazette (which he produced with Jake Holmes), was a commercial flop, spelling the end of the first success of Four Seasons. Gaudio regained success for the group in the mid-seventies, writing hits, Who Loves You and December 1963 (Oh What A Night). In recent years, Gaudio concentrates working in the theatre, producing music for the 2001 production, Peggy Sue Got Married and the 2005 play Jersey Boys (based on the members of Four Seasons), in which he won four Tony awards and a Grammy award.
