This is a fun one that I remember being in our songbooks in music class in Labrador. Newfoundland songs involve a lot of wife troubles, wherein if you're not being forced to marry, you're separated by the sea or wishing one of you was dead. This song involves the latter. I modified the words a bit to what our songbook had.
A friend of my own came to see me one day,
He told me my wife she was pining away;
He afterwards told me that she would get strong,
If I'd get a bottle from dear Doctor John.
I bought her a bottle just for to try,
The way that she drank it I thought she would die;
I bought her another, it vanished the same,
And then she got cod liver oil on the brain.
I bought her one more and she drank it no doubt,
Because she began to get terrible stout;
And when she got stout, then of course she got strong,
And then I got jealous of dear Doctor John.
Our house it resembled a big doctor's shop,
It was covered with bottles from bottom to top;
And early in the morning when the kettle do boil,
You would swear it was singing of cod liver oil.
