Priscilla Presley has vowed never to ''compromise'' Elvis' voice.
The 70-year-old actress - who was married to the star from 1967 to 1973 - insists she would never take advantage of the late singer's legacy so doesn't think she should be criticised for backing a new album which features his vocals with backing from the Royal Philharmonic Orchestra.
She said: ''I hope people embrace it. I know there will probably be critics but I would never ever compromise his voice. Because, it was what it was and it was great.
''Don (Reedman) brought this idea to me in 2013 when I was here playing the mean queen in panto. It was music to my ears. I went, 'We have to do it.'''
Defending her choice to create 'If I Can Dream', she insisted the 'Jailhouse Rock' hitmaker would have loved the collection.
She explained: ''Elvis loved bigness. This is the kind of thing he would have absolutely supported and would have done in a minute.''
The record also features a duet between Elvis and Michael Buble, who Priscilla praised for doing justice to the track.
She gushed to The Sun newspaper: ''The professionalism Michael showed on this is unbelievable. He is a perfectionist. I don't know how many times he rehearsed with Elvis but you feel they are in the same room.
''I can just see Elvis ... he had such a great sense of humour ... going, 'OK, you think that's good? Listen to this!' and Michael replying, 'Well, mmm, let me show you what I got!' It's really good and we are very proud of it.''
