“The first known recording of “Choucoune” was by Roger Fanfant and his Guadeloupean orchestra in the 1930s.”

Afaik none of the Fanfant clan ever recorded Choucoune. Different island, different song - Colby (Martinique)

The first known recording of Choucoune was by the Yank's Katherine Dunham and Ensemble in 1946 (Afro-Caribbean Songs and Rhythms, Decca A-511.)

Both share a phrase of melody with Luboff's Yellow Bird but none of the lyrics can be sung to the other's sheet music, “from the top.”
