Listen to Toby Keith on iHeartRadio

Toby Keith and his friends will be performing before a packed house when they play their fundraiser for Oklahoma storm victims.  Tickets went on sale Friday for the country star's upcoming "Oklahoma Twister Relief" benefit, and were all gone in just over an hour. 

But more tickets could become available once the production for the show is finalized.  Garth Brooks, Trisha Yearwood, and Ronnie Dunn are among the stars joining Toby for the charity event.  Willie Nelson, John Anderson, Mel Tillis, and Sammy Hagar are also on board for the July 6th show, which will take place at the Gaylord Family - Oklahoma Memorial Stadium at the University of Oklahoma in Norman.  The lineup for the event could also grow. 

Money raised through the show will go to The United Way Of Central Oklahoma May Tornado Relief Fund.
