Can anyone help me out with this song which I heard a year or two back in a folk program on BBC Radio2. I wrote down the name of the song and of the female duo who sang it and then cleverly lost the paper.

The song was basically an old (and corny) joke set to music (in the manner of the Bantam Cock, or The Rabbi and the Irish Priest).

The joke basically concerned an old couple approaching retirement, with the man worryiiong about how they would manage for money. His wife points to the row of houses opposite and informs heim that they, in fact, own the houses. She explains that every time they made love she put a few shillings away. He replies that she should have told him what she was doing and then he wouldn't have played away from home, so they could have bought the pub on the corner as well. She has to tell him that she has, in fact, bought the pub too - for the milkman!

I'd love to get a recording of the song if anyone can point me in the right direction.
