Right, here goes. To the best of my knowledge, the song is by Connie Francis and it's entitled "HAVA NAGILA (DANCE EVERYBODY DANCE)
and the lyrics are as follows

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 belev sameach,
uru achim
uru achim
uru achim
belev sameach.

Over the valley
Voices are singing
Bells are a ringing
Dance, everyone, dance

Come to the valley
Run through the clover
Harvest is over
Dance, everyone, dance

Dance where the corn was high
Under a golden sky
Dance where the one was born
Dance, everyone, dance

Whirl and turn about
Lift up your arms and shout
Join hands, skip along
Dance, everyone, dance

Turn left, turn right, hold tight
Lift your feet, the heart will follow
Lift your voice, fill the hollow
Spread your wings like the swallow
Spread your wings like the swallow
Fly away, greet the day
Dance, dance, everybody, dance

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 belev sameach,
uru achim
uu achim
uru achim
belev sameach.

Hope this was of some help to you.
