I think that the top is Matthias Vannelli. He's done many scenes for Kr↑sten BjǾrn
I'm not sure who the bottom is.
There is also a small possibility that I have this video, but I will have to check.
The second film is a classic.
Big Guns. It stars Jeff Quinn, Mike Henson, Rocky Armano, Chris Gray(Grey)/Mike Gray (He went by several names), John Davenport, Jeff Boote, John Rocklin, a very young Kevin Williams (legal), and several others. It's been reported to be one of the biggest gay film of all time. It's a really great movie for the era. I believe it was William Higgins' biggest hit, ever. They released a 20th anniversary edition a few years ago and included a previously deleted scene (the one that you have the link to) that was not included in the movie theaters, where it was originally shown, so that they could fit more showings in at the theaters. It was also too long for VHS tapes, at that time.
I have the video, which I probably downloaded from here. If you can't find it at this site, or Gay-Board.org (under gay movies), PM me and I can upload it. I have it in 540p, which is the best resolution that you can find it in.
