The second line sometimes is given as weave it over my shoulder perhaps just as nonsensical.
I sing the verse below between verse 2 and 3

When I think of the pleasant days we spent in search of treasure trove
And the hours we spent in courting away in Gabbet's Grove;
I did not then deceieve you when I vowed I would be true;
It's not the leaving etc...

I have never dared sing this out as I am convinced the chorus will be hijacked to the tune for the leaving of Liverpool and I have enough trouble not drifting into that tune for the last line of the verse.
Beautiful tune no matter how old it is.
