Iko Iko began as a traditional New Orleans song rooted in Mardi Gras Indian chants, with its nonsense-like refrain passed down through street celebrations long before it reached the charts. The Dixie Cups turned it into a major hit in 1965, and later artists have revived it repeatedly, keeping the chant familiar to new generations. Its simple, repetitive structure and celebratory rhythm explain why it still appears in films, adverts, dance routines and social videos decades later.
