Susan Boyle became an overnight sensation when her incredible audition for the show "Britain's Got Talent" blew away Simon Cowell. Elvis Presley became an international superstar in the 1950's and became a musical icon. Now, some 36 years after his death, the two will be heard dueting on the Christmas standard "O Come All Ya Faithful" through the miracle of modern technology. It's for a good cause.

The Huffington Post reports that the proceeds from the recording will go to the "Save the Children" foundation. Susan is just one of a select few who have been allowed to record a duet with Elvis, the others being Celine Dion and Frank Sinatra. She received a personal OK from Priscilla Presley.

According to the (British paper) the Sun, a source said, "Priscilla asked Susan in person why she should be given the honour. Susan gave a hearfelt speech about how much it meant to her family and how Elvis was her father's idol. It must have worked."
