Slayer blew Venom off the stage that night in San Franfuckincisco...
Rich Hellhound remembered that day in THIS post:
When I saw Venom at the Kabuki Theater in S.F. (with Slayer in '84?), there were a couple of Skinheads harassing Metalheads in the underground parking lot after the show. They were stereotype 'Skins; no shirts, suspenders, Doc Martens, etc., and one was trying to arrange a fight between his buddy (who stood in classic boxer pose, and never said anything) and whichever passing Metalhead would accept the challenge. The "sales pitch" was pretty amusing; it went something like "Just you and him, one on one," repeated over and over. In fact, I think that's literally all the guy said.
Granted my friends and I only paused for a moment to watch one of the exchanges, but I never actually saw a fight. They were still attempting to start something as we drove away. I remember wondering at the time if it wasn't all planned (Skinhead One: "Hey, there's a Metal show at the Kabuki." Skinhead Two: "Cool, let's hang out in the parking lot after the show lets out, and kick some Dirt Head ass!").
Perhaps (and this is a far more interesting theory), there is some sort of cosmic connection between Venom and Skinheads; an ancient, eternal battle that has raged for centuries. For surely the Black Metal Gods must have their adversaries, and would not this nemesis be the polar opposite of the mighty, long-haired warriors?
Oh, and Venom did suck live. I remember being pissed at how Cronos "altered" Countess Bathory (my fave Venom song at the time), so he could sing and play it at the same time. Most of the time he was singing, he wasn't really even playing (just holding chords, as if it were a guitar). Cronos was being spit on repeatedly, and at one point yelled at the crowd, "See that lighting rig up there? If you don't stop spitting it's coming right down on your fucking heads!" I also remember Mantas' lame Karate kicks at the end of the show.
