This is the incredible moment an autistic boy who has never spoken a word in his life SINGS for the first time - at his school concert. Musab Mohamoud has autism and complex learning difficulties and has only ever mumbled words. He was classed as non-verbal and relied on sign language to communicate. But remarkably, during a special music week organised by his school, Musab began forming the words of a song his classmates were learning. He then amazed staff when he performed it alongside other children in the school hall in front of 100 spectators - singing for the first time in his life.
