Are  Paul Bunyan and La sonnambula both Italian operas?
Paul Bunyan (operetta) Paul Bunyan, Op 17, is an operetta in two acts and a prologue composed by Benjamin Britten to a libretto by W. H. Auden, designed for performance by semi-professional groups. It premiered at Columbia University on 5 May 1941, to largely negative reviews, and was withdrawn by the composer. Britten revised it somewhat in 1976 and subsequently it had numerous performances and two commercial recordings. The story is based on the folkloric American lumberjack, Paul Bunyan, with the music incorporating a variety of American styles, including folk songs, blues and hymns. The work is strongly sectional in nature, highly reminiscent of the 'Broadway musical' style of the period.
Il Parnaso confuso Il Parnaso confuso ("Parnassus in Turmoil") is an opera by the composer Christoph Willibald Gluck. It takes the form of an "azione teatrale" in one act. The Italian-language libretto is by Pietro Metastasio. The opera premiered on 24 January 1765 at Schönbrunn Palace in Vienna. All the members of the cast were archduchesses of the Habsburg family and the work was conducted by the future Emperor Leopold II from the harpsichord.
