Roast Chicken Redux; Special Edition; Director's Cut; whatever

I butterflied this whole chicken; then found that The Joy of Cooking I own has no instructions for this procedure. Oops. I cooked it for about the normal time. It came out perfect. I made mashed potatoes and pan gravy and pretty much gained weight. At least I'm not starving myself to death. I made lasagne yesterday; I now have more than enough leftovers to get me through the work week.
