I watched Ragtime's opening number on the Broadway Lost Treasures, and it gave me chills, and I actually cried.
Beautifully staged, awesomely sung, powerfully written.
Absolutely glorious.
Company, too.. it's a great introduction into the world of the show too.. which is what an opening number should do.
I do like All That Jazz too..
Personally, I think I have too much bloom.
