My father used to sing this song, and he sang a verse which began -
"We had two Irishmen on board, Pat Fagan and Dicky Moore
If it hadn't been for those brave lads, we'd never have reached the shore.
They swam   ??????????????????
With a bowline in their hands
???????????????????????
On the banks of Newfoundland.

I am trying to find his particular version, it seems as if his had taken verses from several of the others.
