Last week, Jennifer Nettles and John Glosson's performance of the 1967 Marvin Gaye and Tammi Terrell original ‘Ain’t No Mountain High Enough' earned mixed reviews from the superstar mentors, but fortunately for the Georgia natives, their sparse rendition of 'How Great Thou Art' during tonight's episode of 'Duets' placed Glosson as an overwhelming judge favorite.

"I'm secretly trying to find a way to get you kicked off the show," said a feisty Kelly Clarkson. "You're so damn good! It sounds like you've been singing together forever. Great job! That was so good -- I can't stand you!" The big-voiced singer gave Glosson and Nettles a well-earned standing ovation.

Also on his feet was John Legend, who gave the two a similar assessment. "I felt everything," admitted the 'Ordinary People' singer.  "You sounded so beautiful together. The arrangement was gorgeous. You should be proud!"

Just before taking the stage, Glosson spoke about his personal reason for choosing the original hymn to spotlight his soaring vocals."It's more special because today is the day my mom found out she pregnant with me," said the hopeful.

"The next day my parents lost their oldest son to Leukemia," added a somber Glosson. "I would like to dedicate this song to my parents. And a brother someday I will get to meet."

With his story in mind, Thicke was able connect with the performance on a whole new level. "I have a two-year-old boy myself. I was definitely thinking about my son and your family," said the soul singer. "You had me feel every feeling I needed to feel during that song."

The stellar performance earned Glosson an early lead in week three of competition. "I trust my partners and want to be a part of it. It's their win." said Nettles on her participation in the show. "I just get to hold the flashlight -- as they say in Nashville."
