Scottish singer Susan Boyle is on a hunt to find the best choir in the U.K. to join her for a performance of her festive duet with Elvis Presley. The singer has launched a competition to find a gifted group to help her sing her version of Christmas carol Oh Come All Ye Faithful for a performance which will be aired globally through YouTube.com and social media websites. Boyle tells Britain's Daily Record newspaper, "I'm very excited to find a choir that will sing with the King & I on O Come All Ye Faithful. "No matter what age you are or where you sing or the style you sing in, send in your entries for a chance to win and I look forward to watching your videos." Entrants have to submit a video of their choir singing the track via YouTube.com to be in with a chance of winning. Boyle enlisted the help of 120 pupils at St Rose of Lima School in Glasgow, Scotland to perform the Nativity story in the promo for the festive track, and she celebrated its release by paying the young video stars a visit on Wednesday (13Nov13). Five-year-old Rhys, who stars as Presley in the video, says, "Susan's really nice. I've met her loads of times and she's a really good singer." Music producers used digital technology to combine Boyle's vocals with those of late star Presley on the record, making her one of only a handful of artists to be given permission to record a duet with the late legend.
