Today's theme is "sad song" and this one by American Idol season 7 winner David Cook fits the bill. The song was written for his brother, Adam, who fought brain cancer for over 10 years. I heard this song when he returned to American Idol in 2009 and performed it just a few weeks after his brother's death. I recalled this story about David and it made me cry, cry, cry as he sang. Please watch the video on this page and see this courageous young man continuing the fight against cancer in the very depth of his grief with a sense of humor and conviction.
