That "Diamond Jo" steamboat might help explain the "Diamond Joe come and get me" in lyrics sung by The Georgia Crackers (AKA the Cofer Bros.) on Okeh back in the 1920s. It's a different song from the Lomax one, a hoedown mostly related to "Skillet Good and Greasy".

DIAMOND JOE

Cho:
Diamond Joe, come and get me, my wife died and quit me,
Diamond Joe, you better come get me, Diamond Joe.

I'm gonna buy me a sack of flour, cook you a hoecake every hour,
Diamond Joe, you better come get me, Diamond Joe.

I'm gonna buy me a piece of meat, cook you a slice, once a week,
Diamond Joe, etc. as above

I'm gonna buy me a peck of meal, take me a hoecake to the field...

I'm gonna buy me a jug of whisky, gonna make my baby frisky...

I'm gonna buy me a jug of rum, gonna give my Ida some...
