Listen to Keith Urban on iHeartRadio

Keith Urban says he thinks the audience will be entertained at Tuesday's "We're All 4 The Hall" show.  The theme of the night is "Songtellers," and will feature performers singing and sharing personal stories about either a country classic, a song they wrote, or one they chose to record. 

Urban explains that some participants -- like Reba McEntire and Ronnie Milsap -- aren't known as songwriters, so the theme opens things up beyond a song's creation. 

Vince Gill will once again join Urban in co-hosting "We're All 4 The Hall."  The show's extensive lineup also features Carrie Underwood, Brantley Gilbert, Darius Rucker, and others. 

The concert will take place at Nashville's Bridgestone Arena.  Money raised will go to the Country Music Hall of Fame and Museum.
