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 It premiered at Columbia University on 5 May 1941, to largely negative reviews, and was withdrawn by the composer.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.
La Périchole La Périchole (] ) is an opéra bouffe in three acts by Jacques Offenbach. Henri Meilhac and Ludovic Halévy wrote the French-language libretto based on the 1829 one act play "Le carrosse du Saint-Sacrement" by Prosper Mérimée, which was revived on 13 March 1850 at the Théâtre-Français. Offenbach was probably aware of this production, as he conducted the orchestra of the Comédie-Française from around this time. Another theatrical creation that pre-dates Offenbach's opéra bouffe and may have influenced the piece is a farce by Desforges and Théaulon given on 21 October 1835 at the Théâtre du Palais-Royal.
