She wrote, "I can't stop listening to Mariah's rendition of One More Try. George Michael is a great friend and one of my favourite artists, so I never think that anyone can do justice to his music. But I feel that Mariah really understands every word that he has written. At times her voice is angelic, at times pleading and then, towards the end, it goes into a crescendo reaching amazing heights. I'm sure that George would be very proud of Mariah's version of his much-loved song."
