Here's a report from a friend of mine:
I saw a short performance of the Queen musical on German TV this past Saturday. Besides having the (very staid) Germans rocking in their seats (even the Burgermeister of Nuremberg was stomping and clapping to We Will Rock You), Brian May gave a brief interview at the end in which he said, among other things, that the cast was so good that they didn't even need the Queen members any more to do the music.
Part of being Advanced is always saying that other people playing your music is better than playing it yourself.
My Pixies show review is coming in a bit. There's a lot to process, and my mind is a bit rattled this morning.
