One of our Chamorro Christmas songs is "Iya Belen." The Chamorro lyrics go :
Iya Belen, tåno' Jesus / må'gas na songsong / iya Belen.
The original hymn was a Christmas carol from the Basque region of Spain called "Oi Betlehem." It was written by a Capuchin priest and Pale' Roman de Vera translated it into Chamorro. This performer is singing it in the Basque language, not in Spanish. The Spanish version is "Dulce Belén."
