Susan Boyle, the frumpy Scottish spinster whose amazing voice has become a global YouTube sensation, stunned audiences again on Sunday as she was voted through to the final of “Britain’s Got Talent.”

Singing “Memory” from the musical “Cats,” the 48-year-old overcame initial nerves to produce another command performance, her soaring rendition winning the telephone vote on the talent show.

“You are one special lady, I have to say, you really are,” Simon Cowell, one of the panel of three judges, said after Boyle’s performance brought the audience to their feet.
