From StarWars.com:

“Star Wars: In Concert, a unique multi-media event featuring music from all six of John Williams’ epic Star Wars scores, begins its worldwide arena tour on October 1, 2009 at Honda Center in Anaheim, California.

Narrated live by Anthony Daniels (the actor who portrayed C-3PO in all six films), the production features a full symphony orchestra and choir, accompanied by specially edited footage from the films displayed on a three-story-tall, high-definition LED super-screen — one of the largest ever put on tour. The live music and film elements are synchronized in order to create a full multi-media, one-of-kind Star Wars experience.” [end quote]
