The first time I heard Neil Gaiman read his short story, "The Man Who Forgot Ray Bradbury," it was during his Guest of Honor reading at the 2011 World Fantasy Convention. I don't really like to cry in public, but at some point during the reading, I just gave in, and let the tears stream down my face.
It's an amazing story.
Here is the link to Neil reading "The Man Who Forgot Ray Bradbury." This particular recording is taken from the "An Evening With Neil Gaiman and Amanda Palmer" album. The short story itself will appear in the forthcoming (July) anthology Shadow Show, which is a tribute to Bradbury.
