Susan Boyle became an overnight sensation after her performance on the television program, "Britain's Got Talent" on April 18, 2009. Her rendition of "I Dreamed a Dream" has been viewed by millions on YouTube. When she first appeared on stage, the crowd began booing and hissing. A few bars into the song, as her earthy, pleasing voice took command and soared over the auditorium, the crowd let out a collective gasp, then cheered raucously. She is a 47-year-old Scottish single woman.
