I sure hope you can get to see Diana as LV, she is a sight to behold, her acting is great and her singing out of this world.
You really need to go, this opportunity won't be back for a second run, don't think so anyway.
I'm pretty sure she couldn't do this again.
The strain must be enourmous on her, physically and mentally and on her voice as well.
I really don't know how she can keep doing it, she is fantastic for even attempting to do what sshe is doing.
Just hope you can get to see her, even if you have to crawl there.
