By now the hatred in the room is one huge livid wave, and Iggy singles out one heckler who has been particularly abusive: "Listen, *******, you heckle me one more time and I'm gonna come down there and kick your ass." "**** you, you little punk," responds the biker. So Iggy jumps off the stage, runs through the middle of the crowd, and the guy beats the shit out of him, ending the evening's musical festivities by sending the lead singer back to his motel room and a doctor. I walk into the dressing room, where I encounter the manager of the club offering to punch out anybody in the band who will take him on. The next day the bike gang, who call themselves the Scorpions, will phone WABX-FM and promise to kill Iggy and the Stooges if they play the Michigan Palace on Thursday night. They do (play, that is), and nobody gets killed, but Metallic K.O. is the only rock album I know where you can actually hear hurled beer bottles breaking against guitar strings.
