"December, 1963 (Oh, What a Night)" is a song by the Four Seasons, written by original Four Seasons keyboard player Bob Gaudio and his future wife Judy Parker, produced by Gaudio, and included on the group's album, Who Loves You (1975). The song features drummer Gerry Polci on lead vocals, with the usual lead Frankie Valli singing the bridge sections and backing vocals, and bass player Don Ciccone (former lead singer of The Critters) singing the falsetto part (And I felt a rush like a rolling bolt of thunder / Spinning my head around and taking my body under).
