The version I was taught in 1960 went like this.

Once there was a Chinaman
His name was Chickie Chaloo Japan
His teeth were short, his hair was long
And this is the way he marched along.

Chorus

Chickie Chaloo Chaloo Japan
Cholopy. Olopy, Chickie Chalopy
Chickie Chaloo Chaloo Japan
Cholopy Olopy Chinaman

At last the poor old man did die
And in his coffin he did lie.
They took him back to old Japan
And that was the end of the Chinaman.

Chorus
