Susan Boyle duets with Elaine Paige December 2009 - I know Him So Well

Susan Boyle has recorded a duet with Elaine Paige for this weekend's ITV1 special I Dreamed A Dream: The Susan Boyle Story.

The pair sung 'I Know Him So Well' together, although Boyle is believed to have been unaware of the duet until shortly before the performance, the Daily Mail reports.

Boyle said: "I never thought I would see myself standing on the same stage with such an icon from West End theatre, let alone singing with her as an equal."

The Britain's Got Talent runner-up told the panel that Paige was her inspiration during her first audition on the reality talent contest.
