Here is what he said about it when he sent it to me:
"I just uploaded some footage of Warren Ellis that I've been holding onto since 2006. It was shot on a cel phone - but it features a few minutes from his Night With Warren Ellis event. It was never meant to be professional nor for public consumption - but I figure there are some out there that would appreciate it. I have a much longer clip of Ellis from the same event - but am having troubles converting it into a manageable size for youtube."
