Pero mira como beben los peces en el rio (But look at how the fish in the river drink)
Pero mira como beben por ver a Dios nacido (But look at how they drink because they saw God’s birth)
Beben y beben y vuelven a beber, (they drink and drink and keep on drinking)
Pero mira como beben por ver a Dios nacer. (But look at how they drink because they saw God be born)
(God=jesus. this is a christmas song)
This is a song we sing at Christmas. The birth of God is the birth of Jesus.
I think that this is an attempt to justify their religious identity. In actuality, it’s a bit of a logical fallacy, but they are trying to associate something that is not necessarily proven to be true (birth of god) with something that is constant and happens all the time, and they witness (the fish ‘drinking’ in the river). The artist Gipsy Kings recorded this, and were quite successful– http://www.youtube.com/watch?v=PhSjqnKNgvo
