Susan Boyle reached another pinnacle in her career after producers arranged for her to sing a duet with her idol, Elaine Paige. The surprise was kept a secret from Boyle until shortly before the performance, reports UK's Daily Mail. The pair sang Paige's song 'I Know Him So Well.' After the duet, the 'Britain's Got Talent' runner-up said, "I never thought I would see myself standing on the same stage with such an icon from West End theater, let alone singing with her as an equal." The performance is part of a TV special called 'I Dreamed A Dream: The Susan Boyle Story.'
