I used to be a farmer and I made a livin’ fine
I had a little stretch of land along the CP line
But times went by and though I tried the money wasn’t there
And bankers came and took my land and told me fair is fair
I've also seen it transcribed as "city line". However, that sounds entirely unlike what it is on both recordings I have
I myself thought it was "CB line". jazz007 thought it was "seaweed line", about where the tide comes to.
Anyway, none of these actually tells me anything useful. So Canadians, please tell me what the line is actually about.
