I really enjoyed your performance, it made me feel like I was in South America!
I looked up the lyrics for an English translation:

Grinding coffee

When the evening fades, the shadows are reborn
And in the silence the plantations again hear
the sad love song of the old mill
which in the silence of the night seems to say:

Some kind of heartbreak, some kind of sadness,
carries the sambo* Manuel in his bitterness.
He tirelessly works throughout the night grinding coffee.

When the evening fades, the shadows are reborn
And in the silence the plantations again hear
this sad love song of the old mill
which in the silence of the night seems to say:

Some kind of heartbreak, some kind of sadness,
carries the sambo Manuel in his bitterness.
He tirelessly works throughout the night grinding coffee
