I'm not ready to give up, Jenny. I'm thinking of a song that could be Israeli. Half the audience goes "tumba, tumba," over and over again. The rest sing a very simple melody, but I can't remember it.

Another possibility is Achshav (click for sound sample:


ACHSHAV!

Achshav! Achshav!
B'Eretz Yisroel
Achshav! Achshav!
B'Eretz Yisroel Hey!
Tumba, tumba, tumba
B'Eretz Yisroel Hey!
Tumba, tumba, tumba
B'Eretz Yisroel

(Right now, in the land of Israel!)
