On Sunday evening (Nov. 1), Dierks Bentley and some of his famous friends helped raise more than $600,000 for Nashville’s Monroe Carell Jr. Children’s Hospital at Vanderbilt at Bentley's 10th anniversary Miles & Music for Kids event.

After a celebrity motorcycle ride from Harley Davidson in Columbia, Tenn., to Music City’s new Ascend Amphitheater, Bentley, Florida Georgia Line, Thomas Rhett, Cole Swindell, the Cadillac Three, Canaan Smith and Brooke Eden performed at the brand-new outdoor venue. At the end of the evening, the total amount of money raised through this year's event -- $636,479 -- left Bentley stunned.

"That's a damn six!" Bentley said (quote via Rolling Stone Country). "Our first year was $30,000, and now, 10 years later, there's a six in front of it! This is unreal."

The fundraiser also including a small auction. To date, not including the 2015 total, Miles & Music for Kids has raised over $3 million.

"We go over to the Vanderbilt Children's Hospital every year to present the check and meet some families, and I have some personal relationships with people there after 10 years," Bentley explains. "It's really good to go over there and see how lucky you are to have healthy kids, and if you didn't, this is where you'd want them to be. They have the best staff, the best doctors, they make it feel like home even though it's a hospital."

The singer's oldest daughter, Evelyn Day, was born on Oct. 4, 2008, at Vanderbilt -- the day before that year's Miles & Music for Kids event was scheduled to take place. Bentley says that, that year, "Miles & Music and Vanderbilt took on a whole new meaning."

"I left the hospital wearing my hospital bracelet at 9AM, had not one ounce of sleep, got my clothes and headed out to the Harley Davidson dealership and to start the ride. We did that whole show in a daze of just lack of sleep and bewilderment," Bentley recalls to Nashville's Tennessean newspaper. "... We were lucky to have a healthy baby, [but] it just really changed the way I look at the world and the way I look at the Vanderbilt children’s hospital and how important it is to have a hospital like that."

Miles & Music for Kids was just one of numerous concerts, events and other activities scheduled around Wednesday's (Nov. 4) 2015 CMA Awards, at which Bentley will be performing with electronic violinist Lindsey Stirling. He is also nominated for Male Vocalist of the Year.

"I'm up for Male Vocalist of the Year at the CMA Awards in a couple of days," Bentley told the Miles & Music audience. "But this is way more important than any of that award show s--t."
