Thanks for all the respones and recommendations folks!
Fortunately no one was home or in the garage when it went. Ann was just coming home and the door wouldn't open. When I got home last night I looked around and noticed the spring on one side was not connected. So being the home handy man I grabbed my ladder and some wrenches and started looking at what to take apart. When I noticed how both springs connected together at the center and thought about it for a minute I stopped. The remaining spring was still wound up. I figured that it would unwind if I loosened it and that might not be cool. So common sense actually took over on this one...
The guy is coming over tomorrow morning to fix it. This is a 2 car garage with a single wood door, 18x7, apparently the larger size. So he told me not to mess with it or touch the spring. He's replacing both and resetting the tension and all that fun stuff.
Thanks for the tip on spraying the springs with WD40. I usually lube the worm drive, rollers and the cables but never sprayed the springs. They are rusty. It snapped about 2 turns of the coil from the center. I don't see any debris in the garage so it appears to be a clean break. Bet it did make quite the noise when it snapped. The important car was here with me at work so no schrapnel came in contact with fiberglass

I will be sure to let Ann know you wanted dibs on the parts should I try the repair. You can try and explain your way out of this one at the Rock. You do own tap shoes I hope
