The Unsung Hero Behind "Oh, What a Night" Reviving Four Seasons.
Gerry Polci, former drummer-singer of the Four Seasons, is the primary vocalist on the band's enduring hit "December, 1963 (Oh, What a Night)." Despite the song's popularity, many people still believe that Frankie Valli sings on it. Polci joined the band in 1973 and helped revive their career with hits like "Who Loves You." He also contributed to the vocals, singing high background parts, mids, and lows for all the oldies.
