I was only 16 years old but had been to couple of concerts. I was a little bummed out when they first appeared I think it was Robert Plant moaning about how he hated New Haven. I remember there being a bit of a to do over how loud they could set their amps. The Yale bowl is situated in a in a residential area and the organizers had assure the community that they would keep it at reasonable level what ever that is. Anyway the band didn't like it and they let the crowd know it. Hell, we just wanted to hear them play. Well when they did it was amazing, unbelievable and incredible. If they had a problem with New Haven it didn't show up in the music. And I can't imagine anyone giving a better performance than John Bonham, he was incredible anyone that went to that concert unless they were totaly fried would have remembered Bonham. His hands must have been bleeding when that concerted ended.
