December 9th, 2017. Calvary Presbyterian Church in San Francisco. This is the concert level boys performing. This is a Villancico from Andalusia.
Lyrics:
Gatatumba, tumba, tumba, with tambourines and rattles.
Gatatumba, tumba, tumba, stay out of the straw.
Gatatumba, tumba, tumba play the whistle and the rebec.
Gatatumba, tumba, tumba, drums and bells.
