Work computer wont let me play the video, so I'm not absoulutely sure that its the same one. And yes the video is from the fella who debuted the Grill Barrow or whatever it was on here some time back. He wasn't received very well on here, but I've seen him on another forum for a few years and he is an avid outdoor cook and contributor there.
