Literacy group I visted, they were praising to end their lesson

They were singing the following:

Demos Gracias

// Demos gracias al Senor, demos gracias. Demos gracias por su amor. //
Por las mananas la saves cantan las alabanzas al Cristo el Salvador.
Y tu, mi hermano, porque no cantas las alabanzas al Cristo el Salvador?

Translated version:
Let’s Give Thanks

// Let’s give thanks to the Lord, let’s give thanks. Let’s give thanks for his love. //
In the morning, the birds sing the praises to Christ the Savior.
And you, my brother, why don’t you sing the praises to Christ the Savior?
