David Nail has grabbed a Nashville students choir to help him sing "The Sound of a MIllion Dreams" Thursday night (June 7) at Nashville's LP Field as part of this year's CMA Music Festival.

And rehearsals proved to be so powerful that David almost lost it, The Tennessean reports.

“I don’t think I knew until I walked in here how cool this was going to be,” he told the kids in the chamber choir of the Nashville School of Arts. “I’ll try to hold it together because I could lose it at any moment.”

It was equally powerful for the students, including Charley Woods, who just graduated but came back for this performance.

"I love it!" Charley said. "Meeting David Nail was such a cool experience, and it has only fed my dream of doing this for the rest of my life.”
