11-year-old Brianna Shirley was born with optic nerve hypoplasia and Autism with Aspergers tendencies. She is also legally blind. Brianna is a big fan of country music group The Zac Brown Band and when the lead singer saw some of her YouTube videos, he invited her onstage for a special duet performance. What an incredibly heartwarming moment!
