Request for help with greeting

[Celso Alvarez Cáccamo]

Hello,

Can anyone identify this traditional greeting, which I excerpted from a 
(pretty bad) documentary on human cultures?  It's a Windows Media Video 
file (559 KB):

No sound at the beginning, as I deleted the voice-over.

I've got it in better, DVD quality, in case anyone is interested.

Thank you!
