This is how I learned it when I was a child, and I'm 57 now! My kids laugh at me when I sing this song to my grandbabies!

Once in China there was a man
His name was Chica Raka Chee Chi Cho
The chinese man, he had a wife
and oh they led a terrible life
she cut off his pigtail it was so long
and sold it for a chinese song

Chica Raka Chee Chi Cho chickalero
Bongo lero piggy wiggy wago
Hoco poko hit him in the coco
cherimiah cherimiah chi chi cho

I can't remember the rest!
