Hi,
I've been looking for the rest of these lyrics for ages. I'm pretty sure they're American, but know nothing more. It's a song my mother used to sing, and the chorus goes something like:
I will build a hut for dad, out on the back of the lot.
All he'll need is a table a chair and an old-fashioned cot,
And when you're old as my granddad, and I think you're in the way,
That is where I'll put you, and there you'll have to stay.
Any ideas?
