In 2009, Cornell co-wrote a song with a fan named Rory de la Rosa, who had lost his six-year-old daughter to cancer in 2008, and he was diagnosed with the same illness shortly afterwards. He reached out to Cornell to tell him how much his music impacted his life and also the bond it helped create for him and his daughter, and he sent Cornell a poem called "I Promise It's Not Goodbye". Cornell was so moved that he turned the poem into a song with the same title. De la Rosa gave Cornell permission to post the song online. It was available for free download on Cornell's official website in April 2009. Cornell asked, however, that his fans would consider making a donation in memory of Rory's daughter and to help ease the financial burden of his disease. In 2013, Cornell made the song available for streaming on his official website in honor of the kids who lost their lives in the Sandy Hook tragedy. Links were provided for donations in memory of the victims.
