http://www.childrenscancer.org/zach/ 3 years ago our beloved friend, Zach, wrote “Clouds” to say goodbye & inspired millions around the world. His cause was childhood cancer. His music & story launched the Zach Sobiech Osteosarcoma Fund which is helping cancer researchers make significant progress in understanding the cause of this cancer & how to better treat it. Thanks for helping us fly a little higher. Because you've shared Zach's story, his legacy lives on!
