The sound comes from a 2012 viral video filmed at Queen's Market in London, where Pakistani fish seller Muhammad Shahid Nazir sang a simple chant to sell his fish for one pound. A customer recording spread quickly on YouTube, turning his everyday market call into an internet catchphrase. The attention led to an official studio single release later that year, but the raw market version stayed the most shared. Its mix of sincerity, repetition and melody keeps it alive in edits long after the original video.
