This is a song I knew years ago. I can't remember where I heard it, but it might have been Cathal McConnell or Robin Morton. It's a mixture of song and speech and starts off something like

Now when I was young, a bachelor The brightest e'er you've seen My friends all said I looked So very miserable and mean. Till at last I took unto myself A darling wife alas My friends all said to me Jack old boy you must have been an ass.

It goes on to describe what happens when a father is left in charge of the baby when his wife has to go and visit her mother.

I can remember other bits, but not the whole thing. Anyone know it?
