Boyle sang "I Dreamed a Dream" from Les Miserables in the first round, which was watched by over 10 million viewers when it aired on 11 April 2009. Programme judge Amanda Holden remarked upon the audience's initially cynical attitude, and the subsequent "biggest wake-up call ever" upon hearing her performance.  Boyle was "absolutely gobsmacked" by the strength of the reaction to her appearance.

Boyle's rendition of "I Dreamed a Dream" was credited with causing a surge in ticket sales in the Vancouver production of Les Miserables.

The Press Complaints Commission (PCC) became concerned by press reports about Boyle's erratic behaviour and speculation about her mental condition and wrote to remind editors about clause 3 (privacy) of their code of press conduct.

Boyle left the clinic three days after her admission and said she would participate in the BGT tour. Despite health concerns, she appeared in 20 of the 24 dates of the tour, and was well received in cities including Aberdeen, Edinburgh, Dublin, Sheffield, Coventry, and Birmingham. The Belfast Telegraph stated that "Despite reports of crumbling under the pressure..., she exuded a confidence resembling that of a veteran who has been performing for years".
