...and there's a reason Amboise Thomas's Hamlet hasn't been heard there in 113 years: it's just not a very good opera.
I know. I've seen it, and with a cast that included Thomas Hampson, Ruth Ann Swenson, Judith Forst, and Robert Lloyd. It has three pretty good scenes: Hamlet's mad scene, Ophelia's mad scene, and Hamlet's drinking song. Other than that, forget it; the balance is filler. It's one of those operas, like Faust and Manon, that's best served by being done as excerpts on a concert program.
