In 1995, the young woman participated in Michael Barrymore’s show My Kind of People and performed a song “I Don't Know How to Love Him” from a rock opera Jesus Christ Superstar. In 1998, Susan spent all of her savings to record three singles “Cry Me A River”, “Killing Me Softly”, and “Don't Cry for Me Argentina” and sent them to record labels and TV shows. However, she didn’t get the desired replies or offers. The singer didn’t give up.
She participated in as many local music contests as possible. Boyle’s mother tried to convince her to perform in front of a larger audience than the local churchgoers. However, the talented singer was sure that with her appearance, she had no chances of becoming famous.
In 2007, Susan’s 91-year-old mother died. Remembering her advice, the singer overcame her fears and decided to try out for a TV talent show Britain's Got Talent.
In August 2008, she appeared on the stage of Clyde Auditorium in Glasgow for an audition. At first, the judges didn’t take Susan seriously due to her age and appearance. But when she started singing, everyone was amazed. It was an impressive performance. No one expected an average person to sing professionally. Boyle performed “I Dreamed a Dream” from the musical Les Misérables. All three judges voted for Susan Boyle to stay on the show.
On May 24, 2009, the singer made it into the finals by performing “Memory” from Cats. Six days later, she sang “I Dreamed a Dream” one more time, fighting for the winning title. Eventually, she came in second yielding to a dance group Diversity. More than 17 million people were watching the finals of that show.
The pressure a singer was under during the show reflected on her health. She was admitted to a hospital. People talked about a music career being too harsh for Susan. However, she left the hospital 3 days later and continued performing.
