I know this isn't really a Christmas video, but it is called Wintertime, and it's done by my cousin Christina Christensen and her friend Davin Neb. Their band is called Pieces of April. It was written by Janie Christensen (Christina's mother) and Davin, and based on a true story. Be prepared. It's a tearjerker.
(Oh, and see that book over in the right-hand column, Values Stories for a Young Woman? Christina wrote one of the stories in that book, about how she and her sister Ali are following their musical aspirations, despite battling cystic fibrosis every day of their lives.)
