Toby Keith's Oklahoma Twister Relief Concert has sold out for the second time. Additional tickets that were put on sale last Friday (June 28) after production was finalized sold out within minutes, according to organizers.

The news came just one week after the event initially went on sale on June 21 and sold out in just over an hour. The concert is scheduled for Saturday, July 6 at the University of Oklahoma’s Gaylord Family – Oklahoma Memorial Stadium in Norman, Okla.

Keith will be joined by an all-star lineup that includes Garth Brooks, Trisha Yearwood, Ronnie Dunn and Willie Nelson, as well as Mel Tillis and John Anderson. Rocker Sammy Hagar is also scheduled to perform, and Carrie Underwood will appear via satellite from Nashville. Krystal Keith and Kellie Coffey have also been added to the bill.

Donations for twister relief are being accepted online. To give by credit card, call (405) 523-3598, (405) 523-3597, or the United Way of Central Oklahoma’s main number at (405) 236-8441. Checks may be mailed to the United Way of Central Oklahoma, P.O. Box 837, Oklahoma City, OK 73101 with the notation “For May Tornadoes Relief.”

Verizon is also providing a text-to-donate option before, during and after the concert. Customers of any wireless carrier may donate by texting the keyword REBUILD to 52000, which will give an automatic $10 donation to the United Way of Central Oklahoma’s May Tornadoes Relief Fund.
