That is bittersweet news. Like many other, Star Wars gave me one of my earliest exposures to orchestral music, and is one of the reasons that I listen and play today. I first listened to the music when the father of a childhood friend showed me his soundtrack album and played it for me. I hadn't even known soundtrack albums existed!
Famously, many played joined the LSO due to hearing John Williams' scores.
For the longest time, I assumed that we would only get three Star Wars films with a Johm Williams score. We will get nine, all of them great. How lucky we are.
Where would Star Wars be without John Williams?
I fully believe that the time will come when this composer will be fully recognised for his contributions to film and to classical music, alongside Erich Korngold, the film composer who influenced him. And of course, his own influence on current and future composers will be immense.
