The Siege of Belgrade is a comic opera in three acts, principally composed by Stephen Storace to an English libretto by James Cobb. It incorporated music by Mozart, Salieri, Paisiello and Martini, and is therefore considered a pasticcio opera, as well as a Singspiel in English language, as it contained a spoken dialogue. It premiered on 1 January 1791 at the Theatre Royal, Drury Lane, in London with a great success,[1] featuring many famous singers and actors of the time, such as sopranos Nancy Storace[2] and Anna Maria Crouch, tenor Michael Kelly[3] as well as Shakespearean actors (in spoken roles) such as John Bannister and Richard "Dicky" Suett.
