This I cannot confirm. And you must be the first European on this board to prefer US shows, lol.
I have seen him changing the setlist many times and putting in good rare songs (Mystery Train, Diamond Ring...), and really getting into the show, even the rare stuff like "Hey God". On the oh-so-bad "Bounce" tour the band/Jon gave an incredible performance. Jon lying on the floor in full sweat, shaking his head and grinning like a baby in full-exhaustement after 2 hours 50, and getting up to asks for his guitar and play one more song like "These Days" and thereby make it a full 3 hour show is not what I call auto-robot. I'm not saying there are no autopilot Jons in Europe, but I haven't seen him yet, not really. But then again, I wasn't at Hull.
