Scottish singing sensation Susan Boyle confirmed Wednesday that she would perform for Pope Benedict XVI when he visits Britain next month, saying it was her “greatest dream come true”. Boyle, who was catapulted to global stardom after appearing on a British television talent show, told Scotland's Daily Record newspaper that she would sing at an open-air mass in Glasgow on Sept.16. “It is my greatest dream come true,” said the 49-year-old, a devout Catholic and former church volunteer. She will perform “I Dreamed A Dream”, the song which propelled her to fame last year when a clip of her singing received more than 120 million views on YouTube, as well as the hymn “How Great Thou Art”. “To be able to sing for the pope is a great honor and something I've always dreamed of. It's indescribable,” Boyle told the Daily Record.
