We have a Creedance Clearwater Fan....

This is Benjamin "dancing." He does this when he hears music playing, even if it's a cell phone ringing. The Dance started with a pointed finger being waved, and he has recently add the bouncing of the knees (both while standing like in this picture and while kneeling on the ground) and a little more waving with both hands. PS- sorry about the shaky camera work in the beginning, that was me trying to encourage Benjamin to start dancing.
