Now I’ve got it stuck in my head. I remember singing that while working on a ship once (as an oceanographer, not a codfisherman) and my boss waited until I had finished, laughed, and said:
“sung in as pure a mainlander accent as ever I’ve heard”.
He then proceeded to mock me by de-dialecting and singing the song, something like:
“I am the boy that builds the boat and I am also the boy who typically sails her
I am the boy who catches the fish, and then takes them home to my partner, Elizabeth, sometimes called Eliza”
I did not see the show, but I read the companion book, which mentions my ancestor who discovered Newfoundland (or seized it or something like that): Sir Humphrey Gilbert, half-brother to Sir Walter Raleigh.
