Tommy's always fuddling, he's sae fond of ale
But he's good tae me, I hope he winna fail

(fuddling - fuddled, drunk)

Well may the keel row
That brings the bairns their bread

And the first verse has
Let us have a crackie till the boat comes in

crackie is, I guess, related to the Irish 'craic' - a talk, banter, etc

Come here, me little Jacky
Now I've had me baccy
Let us have a crackie
Till the boat comes in
