This "work" contains copies without enough information. The title might refer to any number of different works titled "Jack and Jill", so this "work" should not be combined with any of them. If you are an owner of one of these copies, please add information such as author name or ISBN that can help identify its rightful home. After editing your copy, it might still need further separation and recombination work. Feel free to ask in the Combiners! group if you have questions or need help. Thanks.
