January 21st 2009 is not a date that Susan Boyle is ever likely to forget. ‘I will never forget it,’ Susan Boyle clarifies, in her unmistakeably Scottish brogue. It was the day that the shy, devout 48 year old stepped for an audition on Britain’s Got Talent. Or to put it another way, the day her world turned 180 degrees on its head. In front of the three-strong panel of judges charged with divining which of this year’s British hopefuls really did have talent, the singing voice of Susan Boyle turned out to be a watershed moment neither she nor anyone involved in the show could possibly have foreseen.
