Susan Boyle has premiered the music video for her duet with Elvis Presley:
Producers used digital technology to combine Boyle’s vocials with those of the late singer for a rendition of 'O Come All Ye Faithful'.
Speaking of the song, Boyle has said: "I grew up listening to Elvis and to sing with him, well, I didn't think it would be possible. Isn't technology brilliant? The track is for my father - and for Elvis."
'O Come All Ye Faithful' will be officially released on December 8 as the lead single to be taken from Boyle's new festive album Home For Christmas.
The video features some very sweet children from St Lima Primary School in Glasgow.
Royalties raised from Boyle's version of 'O Come All Ye Faithful' will go to Save The Children, after the star became an ambassador for the charity.
Home For Christmas will be released in the UK on November 25.
