Toby Keith's concert to benefit the victims of the devastating tornado in Oklahoma is shaping up to be an incredible success. Thanks to a veritable "who's who" lineup of live performers, tickets for the July 6th concert at Oklahoma Memorial Stadium sold out in practically no time. 

Tickets for Toby's Oklahoma Twister Relief concert went on sale Friday (6/21), and the overwhelming demand caused it to sell out in just about one hour. The schedule of performers includes country legends like Willie NelsonGarth Brooks and his wife Trisha Yearwood, Mel Tillis, John Anderson, Ronnie Dunn and rocker Sammy Hagar will join Keith for a night of fun and philanthropy.

Despite the fact that the concert is already sold out, more artists are expected to be added to the lineup and will be announced on a future date. Fans who were hoping to get their hands on tickets may still have an opportunity, as event organizers may release additional  for purchase once production is finalized.

Prioceeds from this benefit will go to the United Way of Central Oklahoma May Tornadoes Relief Fund to aid recovery efforts.

The tornadoes literally hit close to home for Toby Keith. He grew up in Moore, Oklahoma, where the devastating tornado hit hardest. And Toby still calls Oklahoma home, as he lives in Norman. He was in Nashville at the time the twister struck, but returned to his hometown immediately to lend assistance and become a spokesperson for the devastated community.
