Just over a year ago, we brought you the amazing story of Zach Sobiech. Zach was a 17 year old boy who was diagnosed with a rare form of untreatable cancer. Zach wrote a song called "Clouds" to tell his loved ones goodbye. The song went viral and became a hit. Well as Zach continues his battle, a few well known supporters of his decided to do their own version of his song.

And these aren't just any supporters. These are some of the biggest names in the entertainment business. In the video you will see Rainn Wilson, Ed Helms, Phillip Phillips, Ashley Tisdale, Colbie Calliat, Jason Mraz, The Lumineers, Anna Farris, and more. The Office star Rainn Wilson spearheaded the idea, and used his celebrity powers to get some of his closest friends in on the project. Not only that, he used his powers to get the people who Zach loves most in on it as well.

If Zach's own video can touch millions around the world, just imagine what this video will do. It's amazing to see so many people coming together to support one person in his battle against cancer. Not only that but they're supporting the fight to find a cure. Visit his Facebook for more information on Zach and the strides he's making.
