I think this was discovered by the Godlearner Seuss in his poetic travelogue of his journey from Feroda, via the new city built inside Paragua's Walls, to Dagori Inkarth in the 2nd Age, titled "Hop on Pop". The relevant excerpt being:
THING THING
What is that thing?
THING SING
That thing can sing!
SONG LONG
A long, long song
Good-by, Thing.
You sing too long.
