Ok, there's an interview with Kevin Tomkins of SJ from some time in the 80s, where he mentions something called "Private Spy." This entity, or organization, is also thanked on the insert to Ultra's "Zoll" LP. What is it? I'm assuming it's something underground, or potentially illegal, along the lines of early "Color Climax." In that case, I just want to know what the hell it is, NOT see examples. Please explain.
