I heard it that way while growing up, too, but have heard a stringband version (DaCosta Woltz's Southern Broadcasters, maybe?) with something like this:

Polly put the kettle on,
Ginny blow the dinner horn,
Polly put the kettle on,
We'll all have tea.

And a parody of same:

Polly plays the kettle drum,
Ginny blows the slide trombone,
Mama plays the clarinet,
And Daddy's leaving home!

Perhaps someone in one of the old-time music newsgroups or lists could help with this version.
