Henry, and Henrietta

A comment by a friend today - about Henrietta Lack - sparked an old childhood memory of doggrel ending "Henry, and Henrietta". Apparently it was something my Grandfather used to recite to my mother:

They were wrecked on this lonely shore, Henry and Henrietta
These two and no more, Henry and Henrietta
They had no food, fruit or nuts, Henry and Henrietta
They hadn’t anything to build a hut, Henry and Henrietta
They walked along this lonely shore, Henry and Henrietta
But soon there was but one, no more, Henry; well, Henry ate her.

What is even more amazing is that Google has it nowhere :-)
