There are plenty of rumblings that drive-in theaters will be turned into amphitheaters this summer, but it was Keith Urban who made it a reality Thursday 40 miles east of Nashville.

Urban performed a private, unannounced show for first responders at the Stardust Drive-In Movie Theater in Watertown, Tenn., the first performance of its kind in the U.S. He played for a little more than an hour.

The audience—more than 200 doctors, nurses, emergency medical technicians and staff from Vanderbilt Health—was parked in nearly 125 vehicles.

“I did this to say thanks to the healthcare workers who are putting their lives on the line for us every day,” said Urban. “And performing in this environment, with everyone in their cars at a safe distance from one another, seems like an amazing opportunity for everybody to just let go and have fun… And I’m a musician, I have to play!”
