Keith Urban sang in front of folks for the first time Monday night (Jan. 23) at a private record label party at a downtown Nashville barbecue restaurant/club.

And he had quite the all-star audience—Dierks Bentley, Lady Antebellum, Darius Rucker, Little Big Town, Luke Bryan, Alan Jackson and Eric Church were among his labelmates present at the Capitol Records bash. Did Eric have a drink in his hand?

All of the acts got onto the stage at Nashville's Puckett's Grocery & Restaurant—one at a time—to entertain fellow artists and label staffers.

Dierks was pretty pumped to be around Alan Jackson, and Dierks even jumped onto the stage for a pic.

Then, when Alan asked if anyone wanted to join him for a song, Dierks got up to sing and Keith grabbed a guitar, and the all-star trio did classic Hank Williams song "Mind Your Own Business."
