Maybe by working together we can work out the lyrics. You can hear the song at YouTube. There is a long spoken introduction; the actual song starts at about 2:05. Here's my attempt at a transcription. Every ellipsis stands for a word or more that I can't understand. I've numbered the lines for easy reference. Now, who can fill in some of the missing words?

1. Who is Coll Mackenzie? I'll have you understand
2. That I am a ... crofter bound down for Newfoundland.

3. I lost my darling Catherine; she died in giving birth,
4. And to raise three sons without her was the hardest thing on earth.

5. They've grown and gone to Glasgow to brave the factories ....
6. They work as hard ... as a deer yoked to the plough.

7. Now I laboured seven years just to pay my tax and ...
8. When a letter came from Canada that brought the saddest news.

9. My brother drowned off Saint John's in the spring of sixty-three,
10. And his widow wrote to say she'd be well disposed to me;

11. And she sent along a likeness from a ...
12. In her fancy frock and parasol with a sunbonnet on.

13. Now there's nothing here to keep me ...
14. And the fishing's ... lonesome with ....

15. So I set off to Liverpool to work my passage o'er
16. On a leaky trawling clipper called the Queen of Baltimore.

17. And I had no strong oilskins to keep me dry and warm,
18. ... to keep me from the storm.

19. And I arrived in Boston a weak and weary man,
20. And I jumped a ... schooner bound north to Newfoundland.

21. They listened to my story as we sat around the stove,
22. And they wondered at the journey I'd made for sake of love.

23. And they fed me beef and salt cod, sourdough and cans o' tea,
24. And I was hale and hearty when I reached the Saint John's quay.

25. And they showed me to a cabin that stood above the bay,
26. And they laughed and joked together as they went on their away.

27. And the knock was answered swiftly by a woman ....
28. When I asked for Widow Janet, the gloom broke o'er her face.

29. "Now, if you be Coll Mackenzie," the handsome woman smiled,
30. "It is my younger sister that has you so beguiled."

31. She led me to the parlour and there to my surprise
32. Sat my elder brother Angus full ... before my eyes.

33. And the lassie in the likeness was standing by the door,
34. And we all embraced each other, the happiest of four.

35. Then we ... that was sailin' on the bay,
36. ... sons of ... far away.

37. Now my name is Coll Mackenzie and I'll have you understand
38. That I am a Saint John's fisherman ....
