Last night, Susan Boyle returned to the America’s Got Talent stage to debut “You Have To Be There,” a new song from her third album Someone to Watch Over Me. Backed by a veritable string symphony and a spectacular light show, Boyle belted the song square in her Les Mis-style wheelhouse and received a solid round of applause after. “I’m so pleased the audience enjoyed the song. I really loved performing that big number. I was also a little nervous introducing something new,” said Boyle. The diva’s overnight success story in the wake of her 2009 Britain’s Got Talent audition will be made into a musical entitled I Dreamed a Dream that’s scheduled to premiere in Newcastle, England, next March.
