Music soundtrack

That's right--it was originally composed for "One Step Beyond", and pops up repeatedly in Al Adamson's films (even as late as 1978's "Nurse Sherri"). I saw "Blood of Dracula's Castle" years ago, but didn't realize until watching it again recently that Lincoln Mayorga co-wrote the opening theme. Mayorga served as pianist for Phil Ochs during the latter's stint at A&M Records, and plays some quite elegantly eerie lines on Ochs's 1969 album "Rehearsals for Retirement".

I love that song "Next Train Out" that plays at the beginning. It's the best part of the entire movie.
