Peruvian kids singing

Many of you know that 2 summers ago I spent 6 weeks in Peru on a mission trip.  These kids are from the village of San Francisco... I'm not exactly sure what they are singing about.  If you don't give them money they keep singing and follow you all the way to the end of the dock back to your boat.  Luckily we had a few Soles (money) on hand.  :)
