Boy, it must be some show!
Yes, it really is some show!  And so is the current "Hello Dolly" revival.   
But even at $170 regular price, which I got during Broadway previews, it was a good amount of cash for my wallet's taste. 
I can't really understand where all this 21st-century appetite to spend that kind of money is coming from.  But as keeps getting pointed out to me, people have been spending that level of $$$ for hot concerts for decades, and theatre may just be catching up.
