Trace Adkins played Nashville’s annual Fourth of July riverfront bash, and he had to include "Honky Tonk Badonkadonk" for the crowd of 100,000-plus.

“Nothing says freedom like a badonkadonk swinging in the breeze,” Trace told Country Weekly, laughing. “Set your badonkadonk free.”

Meanwhile, Trace is getting ready to set his first album free with Show Dog-Universal Records, with Toby Keith at the helm. Trace says he likes having Toby as his boss. When Trace turned in the album to Toby, the conversation went like this: “Whadya think?” “That’s good.” “Yeah, me too.” “It’s that simple with he and I,” Trace says of his relationship with Toby. “I like the way that that’s how our executive meetings go.”

The album, Cowboy’s Back in Town, comes out Aug. 17.
