Here's a quote I found to answer some of our questions about last night: 

"Scott looked pretty tired and beat. It didnt look fresh, that is for sure. He did sound fine to me though.
The played a full set. He didnt mention anything about his condition, but he did say how sorry he was for all the cancellations and said that their next tour would start on the west coast so he wouldnt be worn out by the time he gets here."  -tremolive
