Before Elsa’s powers were finally explained in Disney’s “Frozen II”, Elsa and her little sister Anna used to listen to their mother sing this tender and beautiful folk lullaby as they were falling asleep. The tale told of a magical river in a far-off land, which would provide all of life’s answers should the water eventually be found. An appealing flute part joins this effortless choral arrangement, with harmony accentuating the text by Kristen Anderson-Lopez and Robert Lopez.
