Two months ago I stumbled on a video on YouTube, now taken down, of John Williams conducting a tribute concert of the music of Bernard Herrmann and Henry Mancini. The concert was filmed by PBS on July 25, 2004. http://www.pbs.org/wgbh/pops/programnotes/. I would love to get a copy of this concert. I contacted PBS but they can't give me a copy due to rights issues. Can anybody help?
