In 1995, Susan Boyle went to Glasgow to audition（试镜）for My Kind of People, a televised talent show popular in the UK. She was immediately rejected. She was nervous during the audition, and felt she didn’t perform well, but her brother said that she was rejected because of her plain looks. Susan was not discouraged and continued to sing at church and at the karaoke nights in a local pub.

Susan suffered a personal loss in 1997, when her father passed away. After his death, Susan put her big dreams on hold to care for her sick mother, Bridget Boyle. The mother and daughter often talked of Susan’s possible fame. Bridget Boyle encouraged her daughter to take part in singing competitions. “She was the one who said I should enter Britain’s Got Talent. We used to watch it together,” Susan later told reporters. “She thought I would win.”

In 1999, Susan used all of her savings to pay for a professional demo（样本唱片）tape, which she sent to record companies. In 2002, Susan began taking singing lessons from voice coach Fred O’Neil.

In 2007, her mother passed away at the age of 91. A neighbor reported that when Bridget Boyle died, her daughter “wouldn’t come out for three or four days or answer the door or phone”. She lived alone with her cat, Pebbles. For over a year, she refused to sing. But in August of 2008, O’Neil urged her to try out for Britain’s Got Talent. Convinced that the performance would be an honor to her mother, Susan auditioned in Glasgow, Scotland. She sang I Dreamed A Dream, a hit song from the musical Les Miserables（《悲惨世界》）, in the first round of the show, which was aired on April 11, 2009.

The 47-year-old Scottish woman's plain looks provided a sharp contrast（对比）to her powerfully beautiful voice. The performance astonished the audience and the judges. Online videos of her performance totaled over 40 million views within a week. Although she failed to win the final of Britain’s Got Talent, Susan Boyle became globally popular. Her first album I Dreamed A Dream has sold over five million copies.
