I've just watched it and I think Jackson Browne was great. I'm always amazed that anyone is able to sing under such circumstances but he managed it with only one hesitation. It seemed like the audience was with them. The only thing that would have made it right for fans was if Glenn had walked out to join them. It's not getting much media coverage but it was a group of old men, dressed black, on a black stage singing an old song. It was understated and well-executed. A fitting tribute.

The Guardian live blogger called it "really endearing" and that seems an appropriate.
