And another thing...
Just a thought that occurred to me as I did my nightly YouTubing:
Why doesn't Wolfgang Wagner revive his own staging of Parsifal? This (or, at least, the finale of which) can be seen in a 1981 performance on YouTube, which I have been nice enough to embed below:
Now, this looks like Wolfgang sort of borrowed Wieland's 1951 staging of the same, but it is still infinitely better than any of the other productions out there. Save, maybe, Wilson's.
I know Wolfgang has gotten old, and he is probably still devoted to the Bayreuth Workshop notion, but he had some stagings which were (if not clever) at least reasonable.
