"Femme Fatale" is a song by Elvis Costello, originally recorded by the band The Velvet Underground. The song portrays a cautionary tale about a seductive and manipulative woman, commonly referred to as a "femme fatale." The lyrics describe the woman's ability to captivate and deceive men, using her false charm and alluring appearance. She effortlessly breaks hearts and plays with the emotions of those who fall for her. The singer warns others to be wary of her as she is known for causing heartbreak and disappointment. The song emphasizes the power and control the femme fatale holds over men, comparing her actions to that of a clown, teasing and toying with her victims. The persona of the femme fatale is portrayed as someone who enjoys playing with emotions, leading men on, and ultimately leaving them feeling foolish. The line, "You're written in her book, you're number 37, take a look," suggests that the woman has a long list of conquests and the person addressed in the song is just another name added to her list. Elvis Costello's version of the song adds his unique touch to the lyrics and instrumentation, bringing his own interpretation to the story. The song serves as a warning to men to be cautious of falling for someone who may bring them pain and heartache, emphasizing the allure and danger of the femme fatale archetype.
