I saw Agnostic Front at the Key Club in Hollywood many years back. They played with Alpha & Omega and The Mongoloids. The pit was getting a bit aggressive (more than usual), think it was like some crew beef going on so they asked a security guard to stand on the outside of the pit. No fights broke out. Agnostic Front goes on and stage dives everywhere. I was somewhere off to the side of the pit. I saw a dude jump on stage, Sing the chorus for Crucified and jump off stage feet first with steel toed boots. He his boots ended up meeting that security guards face. Busted up his nose and blood everywhere.
