HAVA NAGILA
( Israeli folk song)

Hava nagila, hava
nagila, hava,
nagila venis mecha.
Hava nagila, hava
nagila, hava,
nagila venis mecha.
Hava neranena, hava neranena,
hava neranena, venis mecha.

Hava neranena, hava neranena,
hava neranena, venis mecha.
Uru, uru achim,
uru achim belev sameach,
uru achim belev sameach,
uru achim belev sameach,
uru achim
uru achim
belev sameach.

Let us rejoice and be happy
Awaken brothers and sisters with a happy heart.

I wasn't able to find an English version that could be sung.
