With more than 20 years of hits and packed concerts as half of Brooks and Dunn, you'd think Ronnie Dunn would just slide right into performing on his own.

 Not so. He showed up in Las Vegas two days ahead of schedule so his voice would get used to the desert air and he could obsess over details.

On Friday he said he wasn't sure how to balance Brooks and Dunn material, if the fans wanted it, with his new material. He says he'd gotten "lectures from everybody" including from his good friend, Barbara Orbison, Roy Orbison's widow.

Dunn says she told him about anxiety Paul McCartney went through about performing Beatles songs when the Beatles ended. Dunn's first public concert with new material was Saturday night at the ACM Concerts at Fremont Street Experience.

 He showcased his new single, "Bleed Red," during last night's ACMs.
