Napoleon XIV

Jerrold “Jerry” Laurence Samuels was an American singer, songwriter, record producer, and talent agent. Under the pseudonym Napoleon XIV, he achieved one-hit wonder status with the #3 hit novelty song “They’re Coming to Take Me Away, Ha-Haaa!” in 1966. Samuels occasionally revisited the Napoleon XIV character to record other songs, usually comedy records with an insanity theme.
