The origins of Omer Adam's "Hopa"

This is was a great summer hit for Israeli Omer Adam called "Hopa" (or I think it is).

But I am sure it is a well known traditional song rather than an original. Any ideas what is the original song...

Even if you don't know about it I am sure you'll enjoy it just the same

and here in a live version of the same during Ceasaria festival with the Georgian Dance Troupe

It was performed at Eurosong 2010 by Giorgos Alkaios & Friends, so I guess it cannot be a traditional song.

Meanwhile, both adaptation and original were added to the database: הופה {Hopa}
