Duetto buffo di due gatti

Duetto buffo di due gatti (cat duet) is often attributed to Gioachino Rossini as much of the music in that piece is drawn from his opera Otello. According to allmusic

The origins of this work are cloudy, but historians agree that it is not an authentic work by Rossini. It does, however, contain a good deal of Rossini's music, so the attribution is not completely off the mark. The Cat Duet contains elements of 1) the aria "Ah, come mai non senti," from the second act of Rossini's opera Otello (1816), 2) a nearby duet between the characters Otello and Iago, and 3) an earlier work in the same vein, the "Cat Cavatina" of Danish opera and song composer C.E.F. Weyse. The compiler was probably Robert Lucas Pearsall, a British composer better known for his output of hymns. In 1973, the Schott publishing house issued a facsimile of an 1825 edition of the Cat Duet, published by Ewer & Johanning and credited to Pearsall, but bearing the pseudonym G. Berthold.

It is a wonderful and entertaining piece of work.
