Discovery Channel guitar and banjo

[Awais]

Hi There Guys,

There was a Discovery Channel ad which had a song played only using the Guitar and a Banjo (Banjo in the lead). The ad dipicted South American life and said "Discovery Channel" in the end.

I've been searching for it for the last three years but without any luck.

Will someone Pllllllllllleeeeeeeeeeeeeeeeeeease help me out.

I certainly WILL be most grateful.
