There's a rather touching science fiction story of about twenty years ago which recounted a future anthropologist lost among savages in the future Britain. He hears a strange garbled song which goes:

Balasamo, balasamo
Sarnocorpano
Bina mosha sada rosha
Chumila balasamo

And, as he dies of wounds at the end of the story he makes the connection between the devolved residents and their song and the subject of our thread.
