Larson's collection remains in manuscript at Indiana University (as I recall).

Last time I checked - years ago - copyright prevented anyone (including me) from quoting from it.

I think the chorus is entirely innocuous, because it makes sense in the "Sally in the Garden" version - which may be the original, since it's all about Sally getting stung by a bee. If the final word of each stanza in Larson's version (which is "ass") were to be elided, it would open the song to interpolations from the "Lulu/ Susie" tradition.

Just a theory.

The song must have been pretty widespread, with versions reported from Scotland, Kentucky (?), Idaho, and nearly a century later from "Curious Clouseau."

Somebody else out there must know a version.
