Alas, musically I'm like Joan of Arc, "I don't know A from B." So I can't give the tune for this, which is truly beautiful. However:

Come All ye bold seamen, whereever you're bound,
And always let Nelson's proud memory go 'round
And pray that the wars and the tumult may cease.
For the greatest of gifts is a sweet lasting peace.
May the lord put an end to these cruel old wars.
And bring peace and contentment to all our brave tars.
