Mozart composed seven of the ten numbers of the first act, plus some recitative, as well a sketch for a further aria; the extant music amounts to about 45 minutes.
Mozart's urgent need of a poet is attested by his willingness to work with someone, who in his opinion had "not the slightest knowledge or experience of the theatre".
[1] Eventually Mozart realized the hopelessness of the project and abandoned Varesco's libretto after six months because of its silly ending, a farcical travesty of the Trojan Horse legend.
The first stage performance was given on 6 June 1867 in Paris at Louis Martinet's Théâtre des Fantaisies-Parisiennes in a 2-act French adaptation, L'oie du Caire, by the Belgian librettist Victor Wilder [Wikidata], who added a new conclusion, and a musical arrangement by the conductor, Charles Constantin, who orchestrated the music and added other pieces by Mozart to complete it.
[2][3] Fragments from L'oca del Cairo, Lo sposo deluso, and Der Schauspieldirektor have been combined as Waiting for Figaro, performed in 2002 by the Bampton Classical Opera.
