I took my eighty year old mom with me. She chair danced so hard her arhtritis was giving her a fit!.I was worn out myself ..between backround vocals, air bass, and some serious chair dancing of my own I needed to rest. Mike was getting ready to re-define the whole concert experience much the same way he did the music video. Those were the most enjoyable two hours I've spent in a theatre in quite some time. And yes, I left with tears in my eyes...gone too soon.
