What the hell is everybody worried about?  :-) 
I think KC and Tim McGraw are more rock with a country twang and country topics, anyway. You know, my wife left me, the dog died, lets have a beer. I can tell you that I was in the crowd at Red Rocks when GPN opened for Kenny. They played a full on rock set that was received extremely well. I got lots of knowing nods from the peeps around me.
