Does anyone remember this song?

When I first came to this land
I was not a wealthy man
So I got myself a shack
I did what I could

And I called my shack
Break my back
In this green and pleasant land
I did what I could


When I first came to this land
I was not a wealthy man
So I got myself a donkey
I did what I could

And I called my donkey
Horse gone wonkey
And I called my shack
Break my back
In this green and pleasant land
I did what I could............

It goes on and on in this manner, he gets himself a cow called 'no milk now' a hen called 'now and then' a wife called 'run for you life' and the final part is a son called 'my works done'

It really is a nice little 'happy song' - my kids love it.

I am trying to find out what it is called. I have tried the obvious...'when I first came to this land' and 'I was not a wealthy man', etc but nothing has become apparent.

I think the lyrics are corrrect but I would like to find the chords to play it correctly if possible....always a bonus! Anyone got any ideas?
