Well... This is an old thread, but I can't help adding to it. I know the song as Old Auntie Cathy from grade school in California in the '50's. Marais and Miranda were popular at that time and their records were frequently played in the classroom. The verse I remember is:

Old Auntie Cathy she liked to bake,
But I don't think I want to eat her cake,
She doesn't use flour, she doesn't use dough,
And what she uses I really don't know.

"Tisn't my affair, 'tisn't your affair...etc.

The other verse--which sent me to the internet because I was singing the song this morning and couldn't finish it-- started:

Old Auntie Cathy she likes to walk
Her feet take up the whole sidewalk...

It's interesting to me that there are so many verses given here, but neither of these shows up. It was definitely a Marais and Miranda recording we were listening to.
