John Barrowman makes more dreams come true for some very special people. A dare-devil grandad, who has raised thousands of pounds for charity, wing-walks, while a hard-of-hearing student achieves her dream of presenting when she reads the weather on live TV. An ex-soldier, who helps soldiers come to terms with life after the army, gives the performance of his life with the show's orchestra, and a teenager in constant pain gets a wonderful treat - duetting with singing star and Strictly Come Dancing judge Alesha Dixon. Plus which member of the studio audience deserves a song dedication?
