though the term isnt preferd to much, i may be of some help in your search for videos of Deliverance from Demons etc… as is it would generaly refered to, as teh term Exorcist or Exorcism is more refering to controling spirits with spells and other magical rights, real just a control of spirits not actualy much expelling of demons ever take place in those instances. Never the less you would do good to by or track down any DVD or the like relating to A.A. Allen there are several sites available and i would order from most any of them as i know most of them, and i own several Allen videos and other recorded media. Asa Allen was the first to popularize and publish live recordings of Demonic Activity in his meetings one album of teh time was called “Screaming Demons” which range from calm to hair raising. Many of teh sites list what is on the video, healing deliverance etc…., hopefuly im not going on n on and you already have the info. Im a bit of a Demonolagist of sorts I study Demons and specificly their destruction and torment etc….. saw your post and hope i have been of some help. Another name in the deliverance field is BIll Sabritzky. Hope you find some good info.
