A 4-year-old Michigan boy with an inoperable brain tumor now has his own superhero theme song thanks to friends and supporters.
Chad Carr, who is the grandson of former University of Michigan football coach Lloyd Carr, was diagnosed with the tumor in September.
Social media support since then has been overwhelming and on Tuesday, a video of the song, "Chad Tough," was released on YouTube. A group named Ariel, Zoey & Eli wrote and recorded the theme song to help Chad in his battle.
Several prominent figures in the University of Michigan community make appearances in the song, including former football broadcaster Frank Beckmann, the Michigan men's basketball team and Chad’s grandfather Lloyd Carr.
The song is now available for purchase online on sites such as iTunes and Amazon.
