my grandmother also used to sing me a variation of this song. what i remember sounded like this.

kiminero captain kero kiminero cairo
bone ji rigdum [something, something, something]

i was very young the last time i heard it, so i probably have it all wrong, but i thought it was so funny when my grandma would sing it to me. i don't remember there being any english lyrics to her version, just jibberish with a cadence.
