hey penny.
i don't know if what i have is unusual or not because i found it in a japanese bookstore of all places.the cd is titled "the original music from dark shadows deluxe edition".not really sure what the 'deluxe' part is.it has 16 songs plus two 'bonus' interviews.
one was done in 1968 with jonathan,grayson,roger davis,humbert allen astredo,robert rodan and don briscoe.
the other is with david selby from 1969.
if you haven't heard it they did these weird voiceovers of jonathan talking over some of the songs.my guess is that they probably had him dub these during the marketing blitz of 68-70-ish.it was probably released on vinyl to flocks of teenage fans("mom you just HAVE to buy me the new dark shadows' record...barnabas talks on it!").it also includes a few of those early blue whale tunes.
