I was looking through some old pictures today and found some of the”Rock” concert I saw once. The inventor of the Pet Rock, Gary Dahl, was there giving a short talk on the invention of the concept. Chairs had been set up with a rock on each and sheet music in front of them. A local “ham” actor was the Maestro with his made up uniform. The pictures are not of the best quality but will give you a look at the scene. Gary Dahl is the guy with the white collared coat, the other is a local announcer. I have read that that Dahl is now a motivational speaker and there is a resurgence in interest with people wanting to get originals
or some want newer rocks with different paint, faces etc.
