DR JohnG, I haven't read about Ambroise Thomas and his opera Hamlet in some time, but my memory is that the original ending of the opera was the coronation of Hamlet as King of Denmark, and his final lines were something like "My love is dead and I am king." This ending was revised when the opera was produced outside of France; they knew the English audiences would laugh their buitts off.
I do love Ophelia's mad scenel it;s not just a coloratura spectacular, but it reaches real pathos by the end.
