The title pretty much explains it all At the Tinley Park (Chicago) PR yesterday, Chester said that the lead singer was the best man at a wedding, so Chester did the whole show. I have some clips uploaded on my FTP, they're definitely not HQ but I took a clip of like every song they did most are 20-30 seconds. I'll post the link later but if the staff at LPA want to make them exclusive I would be willing to do that.
That's not the same show, Chester came out on Technical Difficulties at several shows. The one where he sang the whole show was Tinley Park on September 1st.
