Thaw undiluted lemonade and orange juice concentrate. Combine bananas and lemonade concentrate in container of electric blender and process until smooth. Combine banana mixture with remaining ingredients; mix well. Pour into plastic freezer containers; freeze until slushy. (If you are pushed for freezer space, freeze mixture in three evenly divided containers; omitting the lemon-lime beverage, freeze until solid and add lemon-lime beverage when ready to serve.) This keeps great in the freezer. Simply partially thaw to serve.

Mix juices. Add sugar if needed. When ready to serve, add ginger ale. Pour over ice and serve.
