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 It premiered at Columbia University on 5 May 1941, to largely negative reviews, and was withdrawn by the composer.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.
Teatro Regio Ducal The Teatro Regio Ducal (Italian, "Royal Ducal Theatre") was the opera house in Milan from 26 December 1717 until 25 February 1776, when it was burned down following a carnival gala. Many famous composers and their operas are associated with it, including the premieres of Mozart's "Ascanio in Alba", "Mitridate, re di Ponto", and "Lucio Silla". The opera house also saw the premiere of Maria Teresa Agnesi Pinottini's "Ciro in Armenia" in 1753; one of the earliest successfully received operas by a female composer. Variant forms such as "Regio-Ducal Teatro" and "Teatro Regio Ducale" are also seen.
