Leave Her Johnny is a traditional sea shanty that sailors sang near the end of a voyage, often while working the pumps for the last time before leaving the ship. Passed down through folk tradition rather than a single songwriter, it has been recorded by many Irish and British folk acts, including The High Kings, whose harmony version helped it reach new listeners online. Short chorus clips now circulate in edits and memes because the farewell hook is instantly recognisable even out of context.
