Canadian exports Barenaked Ladies are among the latest acts to be added to the lineup for this year's Farm Aid benefit concert, which already includes Dave Matthews Band, Neil Young, Willie Nelson, John Mellencamp, and others.

The Ladies join country star Deana Carter as the new additions to the show, which is set for September 12 at the Nissan Pavilion in Prince William County, Virginia outside of Washington, D.C.

Steve Earle, Trisha Yearwood, Sawyer Brown, and Susan Tedeschi are also on the bill this year.

Farm Aid organizers hope that this year's show can beef up its Family Farm Disaster Fund, which will be tapped to help the thousands of farmers in Virginia, Maryland, Pennsylvania, West Virginia, Ohio, and Kentucky who have been effected by this year's drought.

Since Young, Nelson, and Mellencamp founded Farm Aid in 1985, the organization has managed to dole out $14.5 million to more than 100 farm groups in 44 states.
