This was before Robert's voice lost its power. The concert started with The Immigrant Song, and you could hear Robert's wail a second or two before the PA grabbed it and blared it out. The hair on the back of my neck stood up as I realised how powerful his voice was, turned to my brother sitting beside me, went "Holy f-" and then the PA and amps kicked it, and it was sheer bliss for the next two and a half hours. Most exciting concert I've been to, and I've been to many since then.
