The host of TV shows such as "Swap Shop", "Superstore" and "Cheggers Plays Pop", Keith Chegwin has always presented a cheerful TV image, but behind the smile lies another, darker side to this presenter. He has had a serious drink problem, admits to being an alcholic and a workaholic with a high-profile marriage to fellow TV presenter Maggie Philbin. The pressures led to his being admitted to a clinic for treatment for stress and alcohol abuse. Three years later and now sober, he looks back on his life with candour.
