"And Mozart, even, until now
Never thought of once, I vow."
The Count.
"Works that you shall live to see,
Great arch-thief of Italy;
That shall drive you to despair,
Clever Signor Bonbonnière."
Max.
"You may have a hundred years,"
Mozart.
"Unless you with all your wares,"
All three, con forza.
"Straight zum Teufel first repair,
Clever Monsieur Bonbonnière."
The Count was loth to stop singing, and the last four lines of the impromptu terzetto suddenly became a so-called "endless canon," and Franziska's aunt had wit and confidence enough to add all sorts of ornamentation in her quavering soprano. Mozart promised afterward to write out the song at leisure, according to the rules of the art, and he did send it to the Count after he returned to Vienna.
