These are the words I remember.

Iko chiko chickory chan Iko chiko Chinese man
lordy caudy dusty o willopy wallopy chinese o

one day the people of the town went up the hill to roll him down
from top to bottom they all began
to tickle and play with the Chinese man

Iko chiko chickory chan Iko chiko Chinese man
lordy caudy dusty o willopy wallopy chinese o

One day the chinese man did die and in his coffin he did lie
They carried him over to Japan and that was the last of the Chinese man.

Iko chiko chickory chan Iko chiko Chinese man
lordy caudy dusty o willopy wallopy chinese o
