I first heard of and came across "Ah! Vous dirai-je, mamam" when browsing through Lieder, Songs und Gospels 3
which gives two text versions. The first, a children's song, is simply of a child begging sweets from its mother whilst the second, original version is of the triumph of love over reason.
The tune is exceedingly simple being a slow climb up the scale from C to A and then back down again. A good beginners piece which even Wolfgang A. Mozart
was not too proud to base his famous piano variations on.
