Carthy also recorded it on 'But two came by' in 1968, and there he definitely sings the Penguin version. It's also on 'Sailors' Songs and Shanties', sung by Ewan MacColl. Isla St Clair's book 'The Song and the Story' has the same version, but Roy Palmer's book 'Boxing the Compass' has a different, longer(6 verse), more explanatory version, which doesn't have those two lines at all. However, v.1 ends with: Through bitter storms in the height of battle,
          Now mark you well what I do say,
          Where thund'ring cannons loudly rattle
          There's no back door to run away.
