Having traveled through both threads I have only seen something similar once. My man used to sing this while teaching me how to iron (around 1974ish). She was born in 1907 so I've no idea how old it is."Old granny's red drawers, Old granny's red drawers There's a hole in the middle where grandad can fiddle Old granny's red drawers!"
A previous post used "where grandma can piddle" which is not heard before.
Anyone ever heard of this?
