John Glosson - How Great Thou Art - Duets - Video Preview

Here's a video preview of tonight's Duets on ABC. John Glosson reveals why he chose the song "How Great Thou Art" which makes his duet partner Jennifer Nettles cry! Awww.

I know Duets isn't doing well in the ratings, but I love reality singing competition shows. As Robin Thicke said last week, it's like a concert every week with the mentors and their duet partners.
