YES, YES, This Rocks . . . NO, NO, Don't Stop a-Rockin'

Any quasi-rhythmical response is considered approval to a rock band. One can even nod or shake one's head. These are contradictory responses in any normal discourse. But not to the rocker. To the rocker, its the same damn thing. Rocking.

Even terrible dancing is OK. As long as you have the energy.

Trust me, I know/am several of those terrible dancers.
