I have been a huge fan of the Four Seasons since I heard "Rag Doll" for the first time in the summer of 1964. So, this news hit me hard. The full article is here . As explained in the smash hit musical, Jersey Boys, Tommy was the founding member of the group. The other three were Nick Massi (deceased), Bob Gaudio, and Frankie Valli. Below is a kinescope from 1964 with a medley of their early hits. From left, Bob Gaudio, Tommy DeVito, Frankie Valli, Nick Massi If you wish to hear a 1964 live concert (audio only), click here . Rest in Peace, Tommy. Thanks for starting the Four Seasons and for all of the great music!
