We can really only speculate, but I really believe that Memorial address and teddy bear are for her father. Not only does she burst into tears whenever she sings either of them, but the lyrics also point to her father.
In teddy bear, I believe she is singing about the night her father left. She is saying that he left, and her present was a teddy bear in place of her father.
In Memorial address, I believe that she is singing about the night she woke up to a phone call telling her that her father is dead.
These songs always make me cry when I hear them
