The charity concert will be taking place on July 6 in Norman, Oklahoma in the Gaylord Family Oklahoma Memorial Stadium at the University of Oklahoma and will feature the former Van Halen and current Chickenfoot frontman as well as Garth Brooks, Willie Nelson, Trisha Yearwood, Ronnie Dunn, Mel Tillis and John Anderson.

"When Toby asked me to come on board, I immediately said yes!" says Hagar. "He's put together a hell of a concert lineup to help raise funds for the brave and resilient people of Oklahoma. My job is going to be to help them take their minds off their problems and have some much-needed, good old-fashioned fun."
