Would I have picked either one of these two for this, Die Csárdásfürstin [The Csárdás Princess] by Emmerich Kálmán from Sempoper Dresden? The whole thing is amusing. So is Jonas Kaufmann starting a trend? Opera stars will now sing operettas. This one doesn't seem very good, but you can watch it here.
There is a trick to operetta. Oh well.
It's better than this, maybe.
It's too corny for me. Who would have thought that was possible? This is about as corny as I get.
