Led Zeppelin North American tour 1977. Waited for this show for months. We had seats just off the side of the stage where the band went up the steps to the stage. Bonham comes out, loud clapping, John Paul Jones, noise getting louder, Jimmy page is ready to go on the stage and the lights dim. Page has a guy on his left and one on his right. They basically carry Page to the stage and plug in his guitar. He's just standing there oblivious. Heroin does that to you. Robert Plant hits the stage and the band starts playing. Horrible mixing and sound. Bonham does a 20 minute drum solo. Zeppelin, the Hammer of the Gods. Not that night.
