Is it true that..?

Many think that Wolfgang Amadeus Mozart was the original composer of this melody, a misconception[4] reinforced by its appearance as a "correct answer" in the original edition of Trivial Pursuit. However, Mozart wrote twelve variations for piano on the melody (Variations on "Ah vous dirai-je, Maman"), now catalogued as K. 265/300e in the K�chel-Verzeichnis.
