Four of the guys look like one might expect. Kind of the prototypical aging heavy metal rockers. They have some combination of tattoos, long hair, and rough or intimidating looks. But Jay Jay French looks different. With short, well-groomed hair, and relatively staid dress, he looked more like a lawyer than a rocker. He also seemed to be the most sedate of the bunch -- almost like he's not really into it and just going through the motions.
I don't know if it means anything, but I found it interesting.
Here are a couple videos from recent performances (I couldn't find the one that I saw and am was referring to above -- sorry). Judge for yourself.
