The two shining lights in his life were his mother (Julie Walters) and wife, Julie-Ann (Alexandra Roach), who wholeheartedly supported his endeavours.
The roller-coaster ride that was his life was never destined to bring the adulation and success Potts craved.
He thought his dream was gone and a life in Wales running a mobile phone shop was his present and future.
But crippling debts and the chance to win 100,000 ($195,000) drove Potts to take the biggest step in his life - to enter the TV series, Britain's Got Talent.
His initial performance of Puccini's Nessun Dorma in front of Simon Cowell has been watched more than 15 million times on YouTube and has become the stuff of folklore.
So his future was sealed.
One Chance is simply a wonderful story beautifully told.Craig Nicholson
