Thanks for your interest, Gibb. I'm trying to "make sense" of about 400 texts (not different stanzas) of these songs. The three most important facts:

1."German Officer"-type versions were known in America and elsewhere from before 1850.

2. The "Mademoiselle/ Parlez-Vous" offshoot was sung in the British Army in France by 1915 or '16.

3. Most versions that were actually sung (rather than printed in folksong books) were only a few stanzas long.
