Along with the concert was an exhibit of Star Wars costumes, props, production artwork and behind-the-scenes videos from the Lucasfilm Archives. Here is a sampling:
-Full costumes for Jedi Masters Kit Fisto and Plo Koon.
-Pages from John Williams' original hand-written sheet music for "Star Wars: Episode I – The Phantom Menace".
-Han in Carbonite and Chewbacca (well the outfit at least).
Definitely a new way of experiencing the epic scope of the saga. For information go to http://www.starwarsinconcert.com/
The souvenirs are a little pricey and frankly a bit bland, but the performance was worth it and the print program was pretty cool.
