Keith Urban’s Fourth Annual We’re All for the Hall Benefit: Willie Nelson, Vince Gill, Tim McGraw + More – Pictures

Keith Urban's Fourth Annual We're All for the Hall concert -- which exists to benefit the Country Music Hall of Fame and Museum in Nashville -- was held Tuesday (April 16) at the Bridgestone Arena in Music City. Country icons and contemporary acts were in the house to help support Urban's efforts -- everyone from Tim McGraw and Eric Church to Willie Nelson to Vince Gill and more.

Check out these photos from the event showing performances by Roseanne Cash, Brantley Gilbert and Jason Aldean, as well as appearances by Trace Adkins. It looks like a good time was had by all, for the hall, for a good cause.

You can also see some of the candid backstage action, where icons and legends were fraternizing, as well as one of our favorite young country couples. It'll make you feel like you were there, partaking in the fun and festivities!
