The song "December 1963" was released in 1975 by Frankie Valli and the (slightly reformed) Four Seasons. While Valli recieved most of his success as a solo artist, his work with the Four Seasons was generally very popular. This particular title was rereleased in 1993 on the Forest Gump soundtrack. The title then reentered the singles chart and became the longest running single on the chart of all time with it's 50 week stay in the Top 40.
