Star Wars in Peru?

The other morning I was walking to school and passed by a school and could hear the band practicing a march. At first the notes sounded so much like the Star Wars Emperial March and I was thinking how bizarre yet cool to hear a Peruvian school band play that! But soon the notes became more clear and it was more of a Peruvian march than something from Star Wars. Relieving but disappointing at the same time.
