UPC: 8719039007455 What is Star Wars without the music? Music has always been essential to a galaxy far, far away. John Williams has written all the music for the Star Wars movies. "The Main Theme" is the most pervasive and well-known theme in the whole saga. "The Imperial March" isn't just an iconic piece of movie music, it might be one of the most well-known melodies in all of pop culture. With "Across the Stars," John crafted a love song for the ages, a lavish orchestral theme that gives gravitas to an otherwise forgettable romance.
