Like I said in the initial post, I know from friends who promote & produce that he is a very amicable chap...
Him & Hospital seem to have a healthy relationship, coupled with Rodigans involvement with Soundclash where it is standard sets are recorded & released, I would hope it would just be a case of asking Rodigan his permission for release & that would be it, its positive PR for both parties...
It wouldn't be detrimental to ticket sales etc, as everybody who has seen Rodigan knows that a recorded set is excellent to have, but to experience him live is a very special thing that is impossible to capture on a recording.
