Mambo No. 5 was originally a 1949 instrumental by Cuban bandleader Perez Prado, before German singer Lou Bega reworked it with new lyrics for his 1999 debut. His version, subtitled A Little Bit Of, became a worldwide number one hit and a defining late nineties pop song. Its list of women's names and infectious mambo rhythm made it easy to quote, parody and remix. Decades later the hook still circulates in edits, parties and meme videos, where its familiar opening signals instant nostalgia.
