All that having been said, this song is like nothing I've ever heard in a musical before. And it's awesome.
There is a lot going on in this song, and it's a little hard to visualize it all in your mind if you don't know what exactly is happening in the story. Basically, what's going on is that the Bastille was just stormed, and the Revolution has begun. At first the people are idealistic about the outcome, but as time goes on they wonder 'what happened to tomorrow', and why everything is still the same as before the Revolution. It's very powerful, and I love the eerie waltz tempo that constantly surfaces. It's a very strong opening for Act 2.
What happened to tomorrow?
Tell us just who to blame
Villains may come and they may go
But everything stays the same!
