Keith Urban Held Concert for Healthcare Workers

Etonline.com: Keith Urban enjoys playing music and giving back.

The country superstar performed for more than 200 healthcare workers from Vanderbilt Health at Stardust Drive-In movie theater outside Nashville, Tennessee, on Thursday, as a thank you for fighting the battle against COVID-19.

"It felt great to be on a flatbed truck. I salute the very shrunken version of my band last night. Small PA system, everything was downsized," Urban told ET's Rachel Smith on Friday about the special private event. "And of course we're playing to folks in cars or sitting in the bed of their pickup trucks and so forth, so it was a unique experience. I felt like I was actually in the cartoon, you know, Cars? I felt like I was looking for Larry the Cable Guy out there. Tater, I was looking for him."

The singer performed songs from his upcoming album, The Speed of Now: Part 1, out Sept. 18, as well as hits and classic tunes.

Also supporting Urban during his performance was his lovely wife, Nicole Kidman. However, she was spotted sporting a boot -- and it wasn't a cowboy boot.

"She broke her ankle," Urban shared, adding, "But she is a trooper, because there she was last night out there amongst all the folks, huddling around with her boot and her mask on."
