Man did I used to be a Letterman fan. My brother first introduced Dave to me when I was really young. I didn't really know why he was so great, but I knew he was. If that makes sense. I really should be watching some of his final episodes.
I think I watched this cover of "Masters of War" as it was originally broadcast. I'm no Pearl Jam fanboy, but remember being greatly affected by this performance in 2004.
