You're welcome, Sheila, and Cool Beans.

I love doing work like this.

Thank you Sheila for providing the opportunity, Joe Offer for revising the title and finding those other examples, and Cool Beans for letting folks know that that song was part of the day camp repertoire in New York around 1955.

For the record (no pun intended), I feel that I should mention that the drawings that Trent John used in her book were clearly of Black girls and Black boys. In addition, the JSTOR reference to "Sissy In The Barn" as a "plantation song" strongly suggests that at least this version of the song is of African American origin.
