Let's be honest. It's a lot of work to put on the show that Jon puts on every night. He's got more energy than Bahgdad (at least at the moment). The man can flat out entertain, but he's getting tired and this is an easy way out.

"Is it really about the fans, Jon, or are you just takin' a break?"

*For the record, I loved the accoustic show in Minneapolis and certainly recommend it*
