George Lucas leads tributes to Carrie Fisher at Celebration, including a speech from her daughter Billy Lourd followed by no less than John Williams conducting the concert version of Leia's own themeas well as other classics to commemorate 40 Years of Star Wars. Sadly, I had to remove the five-minute tribute reel video due to over-zealous copyright holders of a popular song used as background - you'll find this part on the official channel.
