 "Hamlet" (Vienna, 1874), an operetta by Julius Hopp, who adapted many of Offenbach's works for the Austrian capital, is a comic parody of Thomas's artistic methods in the opera.Baritone Titta Ruffo performed the title role with bass Virgilio Lazzari as Claudius and Cyrena van Gordon as Gertrude for both the opera's Chicago premiere and on tour to New York City with the Chicago Opera Association in 1921.Afterwards, the opera fell into neglect.
