Perhaps it's not a top priority? I'm not going to keep questioning what you say though. Of what was said, I to believe that he is a hoarder. A while back Sam_Webmaster asked if Kdh would lend him a copy, never happened. Then about a year later I asked for the film, and he said "I will be at my house for 10 days in the front end of October. At that time, lord willing, I shall set upon the tape." he never got back to us after that statement was made. So it's really unknown whether he set upon the tape or not, or if he even did look for the tape. But it would be nice if he at least responded in someway.
This is why I hate RO, someone claims to own something not yet seen by the public who is hording Zep footage/audio. They're not even sharing it with the Zep community. I mean that's quite ridiculous if you ask me. It's one thing if one recorded a concert/show, but this is not the case.
