Yes, it was cold and outdoors. Adam's voice was not up to par, a lot of notes were lower. Just listen to Fever, and you will hear the difference.I think the whole band had been sick though. The next night in Peoria he was back in form.!!
Anonymous, thanks for the info. Even though he was ill and some notes were lower, he still sounds fantastic. I find it incredible his voice has held up so well after so many concerts.
