Still one of my favorites

The last of Mozart's operas with a libretto by Lorenzo da Ponte, Cosi fan tutte, was given only five performances in Vienna, mostly due to the fact that Emperor Joseph II died during its run in 1790. Its first British performance was in May of 1811 at the King's Theater, with Nancy Storace's common law husband, John Braham, singing the lead tenor role of Ferrando.

It is believed that Mozart may perhaps have had Nancy Storace in mind for the role of Despina, as she and her brother, Stephen, along with several other of their British colleagues were working to present Mozart with a commission for two new Italian operas for the King's Theater in London. The commission arrived while Mozart was away on his last German tour in the fall of 1790, and for reasons not really known, he declined it.
