Hi, my dad who is from Lancashire and sang this song to us along with I'm a wee melody man but the way I remember is this way:

In China once there lived a man
His name was Chika-Racka-Chee-Chi-Chan
His head was big and his feet were small
And this poor Chinaman couldn't walk at all

Chika-Raka-chee-chi
Choo Cock-a-lorum
Cando, lorum, ninny pinny nap
Cat go, you go, etty cotty kitty ko
Ditty pie, Ditty pie, Chika-Rack-Chee-Chi
   

Talk about not being politically correct! But I'm in my early 60's and I remember this; that little golliwog from the jam jar lids and I had a book about ten little Ni***r boys sitting in the sun.
