Not only did he write and produce for the Frankie Valli and the Four Seasons, but he wrote and/or produced for Michael Jackson, Neil Diamond - 6 albums, Diana Ross,Nancy Sinatra, Barry Manilow, Eric Carmen, Roberta Flack, Peabo Bryson, Barbra Streisand, just to name a few. Without his songs the Four Seasons and Frankie Valli wouldn't have risen to the top and been able to stay there.
Bob Gaudio must be credited with a huge amount of the success of the Four Seasons. He wrote their first number one hit and was also the creator of most of their other hits, including those that made them most successful. Without his creative input, the group would not have hit the heights of success that they did.
I strongly believe that Bob Gaudio was the brain child for the Four Seasons. He was one of the main founders and wrote most of the music that helped them become so popular and most of their biggest hits. . Especially the first single that helped make them a household name.
Yes, Bob Gaudio was the brain child of the Four Seasons, because he was the one that wrote the songs. Sherry Baby was the song that broke the Four Seasons into popularity in the first place. Bob Gaudio was the one who really made them famous, because song writing is the most important thing for a pop star.
No, Gaudio's role in the Four Seasons included the keyboard and backup vocals. Gaudio played an invaluable role, as he wrote and produced music, but he is no more responsible for the success of the group than any other band member. Gaudio's contributed to the success of the band with his artistic ability, but it is the unity of the band members that made the Four Seasons great.
