It's a Cannell program, but I don't know whether he owns the rights or the studio (can't remember which one it was) does. It was most recently shown on the History Channel (as Black Sheep Squadron, the syndicated title). Great show.
Actually yep I did know that. It's amazing to see the work this guy has done. Funny that you should mention his name as I just started watching West Wing Season 2 and he showed in there, I thought how cool is to see this guy again!
