Susan Boyle's publicist said the singer resumed performing as part of the "Britain's Got Talent" concert tour after canceling two appearances so she could rest.
Although she performed with other "Talent" finalists at three concerts last Friday and Saturday, she canceled two others Sunday after she was advised to get some rest.
Boyle returned to the stage Monday night in her native Scotland and was greeted by thunderous applause from about 6,000 fans, her publicist told People.com.
"Halfway through the first song they were on their feet giving her a standing ovation, and they remained on their feet the whole way through," the representative said.
Boyle's first album is expected to be released by Christmas, People.com said.
