Not the most PC version, but this is the one I learned in the mid sixties when we lived in Chicago, US. Not sure about somne of the words.

Once in China there lived an old man
Whose name was chikka-lakka-luka-kan
His legs were long and his feet were short
and he could neither walk nor talk, oh . . .

Chikka Lakka Luka, Chikka Lakka Lorum
Condum florum bulla bulla way
Oka Oka itchy cry, itchy cry
Diddy-by, diddy-by shingo . . .

He had so many servants to carry him about
That everywhere he went, the epople would shout
Here he comes, and there he goes
The Chinaman with the monkey's nose

Chikka Lakka Luka, Chikka Lakka Lorum
Condum florum bulla bulla way
Oka Oka itchy cry, itchy cry
Diddy-by, diddy-by shingo . . .
