Hard to say, but I know that on July 22nd 2011 in Vienna Jon was on TOP of the game. Things came so naturally, just a pure pleasure to watch. 28 songs, rarities like Wild is the Wind or Hallelujah, almost 3 hours - they even missed the flight and spontanously stayed in town until the day after.

Want a real gem? This in front of 50.000 was ecstatic. Watch this middle part of "Saturday Night" from 2:45. It's a cool close-up. This was a time when Jon apparently felt something, not robo-Jon.
