The Country Music Hall of Fame and Museum is one of the most treasured buildings in Nashville, and now it's getting some help from several musical friends. The third annual All for the Hall benefit has been announced in Los Angeles, with both return and new guests expected to appear to help raise funds for the coveted building.

Vince Gill and Emmylou Harris, who have performed at both previous All for the Hall concerts, will return to the Nokia stage again this year, where they will be joined by Sheryl Crow and Zac Brown. The benefit, which will be held on September 13, will once again be set up as a guitar pull, with surprise guests expected to be added to the line-up.

The Country Music Hall of Fame and Museum holds a special place in Vince's heart. "It's where it all comes from," the Hall of Fame member explains. "It's the history and what we're preserving. Any day I can do something for this organization is a good day."

The home to movie stars may seem an unlikely place to draw thousands of country music fans, but L.A. is actually an ideal location to raise the necessary funds, according to Museum Director Kyle Young.

"Our 2009 All for the Hall Los Angeles debut gave us an opportunity to focus on West Coast country music history and remind our guests that these artists and executives and their songs are a part of the story we both preserve and teach at the Museum," he tells the Bluegrass Journal. "We are very grateful for our warm welcome the past two years and look forward to seeing old friends and making new ones in September."
