The rare shit is pretty damn hard to find.. First of all, Priest never seemed to have the grasp the past mentality, since the old video footage does not exist. Dont think JP will be conjuring up Priestology I & II any time soon. Kinda of a shame no?  Here's the Rare in Order via Video:

75 Old Grey Whistle
78 Tokyo
80 Green Manalishi Clip
82 Vengeance
83 Dortmund
83 US Festival
Sorry Turbo - Dallas 86 doesnt make it..

Thats it.....
