Sammy Hagar has been added to the growing all-star lineup of Toby Keith's Oklahoma Twister Relief Concert.
Hagar, who is in the middle of his "Four Decades of Rock Tour" in honor of his 40th anniversary, will join an all-star lineup that includes Keith, Garth Brooks, Trisha Yearwood, Willie Nelson, and Ronnie Dunn.
The event takes place at the University of Oklahoma's Gaylord Family-Oklahoma Memorial Stadium in Norman, Oklahoma on July 6.
Proceeds from ticket sales are being earmarked to benefit the United Way of Central Oklahoma's tornado-relief efforts. Nearby Moore, Oklahoma lost 24 residents when a series of deadly tornadoes hit the state on May 20.
Hagar is currently working on his next studio album, which will reportedly include a cover of Depeche Mode's "Personal Jesus," as well as appearances by Neal Schon of Journey and Hagar's surviving Montrose bandmates.
