“December, 1963 (Oh, What a Night)” is a hit single 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 1975 album, Who Loves You.
The song features drummer Gerry Polci on lead vocals, with usual lead Frankie Valli singing the bridge sections and backing vocals.
The song was originally about the repeal of Prohibition with the title of “December 5th, 1933,” but the lyrics were changed at the urgings of Frankie Valli and lyricist Parker. The song became a nostalgic remembrance of a young man’s first affair with a woman.
The song is an up-tempo, piano-led dance song with a distinct and easily recognizable opening drum and then piano riff. It is written in 4/4 and in the key of D-flat major.
