I heard parts of this on a radio program last night and it gave me the shivers.
If you want to find the sound-track of the broadcast you can search for it....and if you don't have 30 minutes you can fastforward to the part where they play Ch. 19, 20, and the end of 21.
(It is called "Coming Soon: part 3")
There are more clips from the archives, but you'll be well rewarded for your pains!!
IF I had any money I would buy as many as I could!! (BUT they are incredibly expensive!!)
