I too have been searching for this song. I believe it is a Music Hall song and indeed that is the reason I am trying to find it.
The version I remember is the one quoted by Rusty Dobro Aug 2006. Only I have some more to add some more as incomplete as it is.
A farmer who has fathered many children is responding to a question by a neighbour
Now you've got all your kids
And I can't get one.
Won't you please tell to me,
Won't you say how it's done?
I gets up at six when I hear the alarm
And after I've milked all the cows on the farm.
I go for a ride on my bicycle
I get around on my bike...
....
