A self-confessed amateur historian, Gregg's fascinating yet, at times, tragic WDYTYA? episode focused on revealing the mystery and misfortune of his maternal great grandfather.
Peckham-born, Gregg describes himself as a "grafter" and hoped to find "a long line of working-class scallywags" amongst his family tree. Instead he uncovered affairs, heart-breaking accidental deaths and institutionalisation. We are very much looking forward to hearing about his intriguing family history and all the research that went on behind the scenes.
