I was led to believe that this show was heavily doctored to get Scott's voice on par just to salvage the performance. Same case with the live versions on the record (vaso, btl, and hd).
I seriously doubt they heavily doctored the whole thing. There were one or two songs that had timing issues that they needed to salvage, but other then that I seriously doubt that they sat there auto-tuning the whole performance. I deffinitely heard him go off key once or twice.
And we've all got to remember, from soundboard to computer to dolby digital sounds a lot better than soundboard to PA system to bootlegers video camera.
Also, if I recall correctly, Chicago was regarded as one of the better shows earlier this year.
Maybe I'm just living in a fantasy land, but I don't think they modified it
too much. They definitely altered some of it, but I don't believe all of it.
