A students' association in Belgium tells us (in Dutch):

The 102 stanzas of the original Krambambuli

Lyrics: Christoph Friedrich Wedekind, 1745
Melody: folk tune from the 18th century (Otto Deneke, Göttingen?)

The chorus is "Krambimbambambuli, Krambambuli!". In the German version the last two lines were repeated afterwards. In the first version of 1745 there were 49 stanzas. Two years later Wedekind published under the pseudonym Crescentius Coromandel the final version of 102 stanzas.

The 102 stanzas follow as on the Ingeborg site, which additionally has the prologue ("Vorbericht") and some explanations by Wedekind, both very interesting as well.

Summary: Ingeborg's version is probably most authentic.
