Ironicly, Letterman was endorsing the new Warren Zevon album about a week or two ago, and took some time to endorse it again last night. Personally, I enjoyed Letterman's tribute. Warren was a great friend to Dave as well as Paul Shaefer and I found it interesting to here what Dave had to say about such a personal matter. Close to a year ago, Warren was a guest on Dave's show and performed some songs. That appearently turned out to be one of his last performances. They showed the clip of one of the songs he did that night. I wish I could remember what it was (if anyone else knows, I'd like to know). He truely was a great musician and a great person!
