Heat the oven to 350 degrees F. Mix all of the ingredients, except the bacon and marmalade, together. Spread the mixture in an ungreased loaf pan, 9 X 5 X 3-inches. Crisscross the bacon slices on the top of the meat mixture and spread the marmalade over the whole thing. Bake, uncovered for 1 to 1 1/4 hours. Drain off the excess fat and let stand for 5 to 10 minutes before slicing. Note: The bananas add a unique, almost mysterious flavor and a special moistness to this elegant meat loaf.
