I keep reading in many articles about the Immaculate Conception that there is this hymn in Spanish that used to be sung in America, written by the first Franciscan missionaries. I know one hymn that is similar but still different. Does anyone know any sources and where I can find the music?

Alabado y ensalzado
Sea el Divino Sacramento,
En quien Dios oculto asiste,
De las Almas el sustento.
Y la limpia Concepcion
De la Reina de los Cielos,
Que quedando Virgen Pura,
Es Madre del Verbo Eterno.
