The oringinal (from original 1933 sheet music) indicates "Old Black Joe"

It is NOT a matter of being politicaly correct...it is the WONDERFUL aspect of music that is played, listened to, repeated...and the nature of the human mind to draw meaning from our surroundings and experiences.... the words are HEARD and INTERPRETED by each individual person in a their own unique way.....(Why "live" is so much more enjoyable than "canned")

My father, as a boy, interpted the lines to the song "Old Black Joe" as "Old Black Toe." In rural Colorado he was a teenager before he saw a "black man." However, he had stubbed his toe, and it had turned black, and it did require him to move slowly, and say "I'm a comin' I'm a comin'" when he was called.

It ain't got a darned thing to do about political correctness....except the sickness of today that causes one to even consider it as such.

Most people of the 1930's would have been VERY familar with the reference.
