*Jackie Evancho's* tone is so perfect she brings out the flaws in other singers' voices no matter how good the the other singer is. Another example of this is playing Celine Dion singing 'My Heart Will Go On' at the same time as Jackie singing it. You can hear the 'Canadian Twang' in Celine's voice compared to Jackie.
*Jackie Evancho's* fans usually prefer her voice to any other singer. I'm sure most of Sarah's fans feel the same about her. Whatever your preference it was very nice of Sarah to go out of her way to do this duet with Jackie.
Здесь хорошо… Взгляни, вдали огнем Горит река; Цветным ковром луга легли, Белеют облака. Здесь нет людей… Здесь тишина… Здесь только Бог да я. Цветы, да старая сосна, Да ты, мечта моя!
