It seems ABC Classic FM is broadcasting Wagner's ring cycle, with one instalment each Sunday evening. The station streams online so anyone who wants to listen is able to, if they can get the time and day right.

I have never heard Der Ring des Nibelungen before, only a couple of excerpts, so I will be listening with great curiosity. Admittedly my preferred format for opera is 'audio-visual, with subtitles' but I still want to hear this.
