'Family Guy' Through the Years - S16-E16
Factual error: In the scene at the Disco, Peter and Quagmire both transpose "Viet Cong" but with "Donkey Kong." However, the segment is supposed to be taking place in 1973, meanwhile "Donkey Kong" wasn't released until 1981.
'Family Guy' Through the Years - S16-E16
Factual error: When the guys enter the disco in the 1973 segment, "A Fifth of Beethoven" by Walter Murphy is heard playing; that song was recorded and released in 1976.
Chosen answer: It's a real song called "Elvira". Originally by Dallas Fraizer in '66, however, this version seems to be the Oak Ridge Boys cover version. However, the mega lesbians skip the verse and just sing the chorus after the opening line.
