Panic!

It was the scariest show (of course I was only 8 years old) but even to this day I recall the opening with the cracked glass. Does anyone know where I can get copies of the show? I've looked on amazon and ebay without any luck. The one episode I recall was a painter or mechanic or somebody like that who was working inside a water tower. He got trapped and had to be rescued. But he was petrified and went a little nuts and the guy who rescued him had to subdue him in the dark inside this metal container. It was creepy and made me claustrophobic just watching it. I recall that he threw a wrench at his rescuer and the way it clanged on the side of the tower scared me.
