This is a potpouri for piano, violin, clarinet/flute,
bassoon/violoncello and guitar which is known to have been performed
in Vienna circa 1815. It contained some passages, jam-session like, by
Giuliani, Hummel and Mayseder. It uses themes from several operas:

Hadrian
The Magic Flute
Les Deux Jounées,
La Vestal.
The Marriage of Figaro
Don Giovanni

and one Austrian folk song titled Gehn ma ham, bleim ma do.

I recall reading an article in which the precise themes used were
quoted, but I do not recall where and when it was published. Any one can
refresh my memory?

Thanks much in advance.
