Zaldivar's song (Indian-Creole dance) is probably the original, but I think it differs somewhat from the Roger Tincknell lyrics given by Chico.:

El Humahuaqueno
Llegande este carnaval quebradeño mi choritay (2x)
Fiesta de la quebrada Humahuaqueno para cantar
elque charango y bombo carnivalito para bailar
quebradeño Humahuaquenito quebradeño Humahuaquenito
Fiesta de la quebrada Humahuaqueno para cantar
Elque charango y bombo carnavalito para bailar.
(I have assumed that these are Zaldivar's lyrics)
