"A Drop of Nelson's Blood" is a sea shanty, also known as "Roll the old chariot along" The origins are unclear, but the title comes from the line: "A drop of Nelson's blood wouldn't do us any harm". Often described as a "walkaway" or "runaway chorus" or "stamp and go" sea shanty, the song features on the soundtrack of the 2019 film Fisherman's Friends. The chorus comes from the 19th century Salvation Army hymn, 'Roll the old chariot'. This song developed into a shanty.
