What Sting said is:
"Caramba", "Arriba", "Un Cerveza" ... Aya ya ya ya ya ayyyy!!!
Spanish, I mean mexican words, at the begining of "Regatta de blanc" finally was found by "Georgygirl"... For me was difficult to understand the last word, but she explain me "Un cerveza" was that word, because is a usually way to said, by mexicans, a cup of beer and after they says the "Aya ya ya ya ya ayyy!!! 8)
