According to an ad from BMG Australia a duets album featuring Sony/BMG artists with Elvis on his Christmas songs isset for release for Christmas 2008 under Sony /BMG’s “Hits & Stars ”campaign.
The ad mentions Olivia Newton John, Cliff Richard, Adam Harvey, Guy Sebastian, Shanon Noil, Jessica Simpson, Leann Rimes and Carrie Underwood as persons who recorded a duet for the album.
Updated August 6, 2008:
Elvis Australia informed us that Guy Sebastian and Shannon Noll will not be included. BMG Australia did consider these artists for inclusion on the Australian release of the album, but it won't be happening. "You will find that only female artists, mainly 'out of Nashville' will be included on the album in any county, certainly Australia. So Olivia is the only likely addition to our release".
