"Clouds," a song by 17-year-old osteosarcoma patient Zach Sobiech
"Facing months to live, 17-year-old Zach is turning to music," according to the notes accompanying this YouTube video, "writing and performing songs as a way to say goodbye to his friends and family".
One of those songs is "Clouds."
Zach's family founded the Zach Sobiech Osteosarcoma Fund to "fund research for the cancer that is taking his life, in hopes that kids diagnosed tomorrow will have a better chance for a cure."
