Weela Wallia - Clancy Brothers

There was an old woman who lived in the wood,
Weela weela wallia;
There was an old woman who lived in the wood,
Down by the river Sallia.

She had a baby six months old,

Down by the river Sallia.

She had a penknife three foot long,
Weela weela wallia;
She had a penknife three foot long,
Down by the river Sallia.

She stuck the knife in the baby's head,
Weela weela wallia;
The more she stabbed it, the more it bled,
Down by the river Sallia.

Three big knocks came a-knocking at the door,
Weela weela wallia;
Two policeman and a man,
Down by the river Sallia.

"Are you the woman what killed the child?"
Weela weela wallia;
"Are you the woman what killed the child
Down by the river Sallia?"

"I am the woman what killed the child."
Weela weela wallia;
"I am the woman what killed the child
Down by the river Sallia."

The rope got chucked and she got hung,
Weela weela wallia;
The rope got chucked and she got hung,
Down by the river Sallia.

The moral of this story is,
Weela weela wallia;
Don't stick knives in baby's heads
Down by the river Sallia.
