[I recieved the following recipe from Kelly McGahey @carleton. Ca, however there wasn't a proper mail address on it and I thought people might be interested so i've posted under my name.] [Mark - Co-Mod]
Here's one out of the "Carleton Cooks" community cookbook, this recipe credited to Patrick O'Reilly.
Cream sugar and margarine and beat until light and fluffy. Add eggs one at a time, and beat well. Add flour. Beat in Realemon and 7 Up. Pour batter into well greased and floured Bundt pan. Bake at 325F for 1 1/4 hours.
