Ghost of Christmas past: Susan Boyle duets with Elvis for charity single

Susan Boyle felt the spirit of Elvis Presley when she recorded a duet with him.

The 'Britain's Got Talent' star is lending her vocals to a recording of the late rock 'n' roll legend on his version of Christmas carol 'O Come All Ye Faithful', and she is convinced his ghost paid her a visit while she was performing the track in the studio.
