I'd been looking to source the Jim Gianatsis videos for a while now and was getting close to just contacting him directly about them - and it turns out he or someone acting on his behalf had gone and put them online:
Iron and Lace II. Cori starts at 20:27.
And, more interestingly, what's apparently a Youtube-safe version of Garage Girls? It's really a different video altogether from the Vivid/Peach release - same title, same models, same shoots, but mostly different (and safe for work) cuts. More of what you'd expect from a "behind the scenes" look than the more commonly seen version which is mostly just a showcase of nakedness. Cori starts at 22:47 (her first scene appears in both versions).
I'm really curious about what's going on here. Did some more searching around and apparently there's a "director's cut"? Which one is which? I have the physical Vivid DVD and it doesn't indicate one way or the other.
