The Toby Keith tribute/benefit concert that will air on NBC has added some big-name performers… At first, the performers included Luke Bryan, Eric Church, Ashley McBryde, Carrie Underwood, Jelly Roll, Darius Rucker, Lainey Wilson, Parker McCollum and The War And Treaty. That would be a full all-star roster right there, but they weren’t done announcing names. Also on board for what is turning out to be a massive event: Trace Adkins, Jamey Johnson, Riley Green, Ashley McBryde, Priscilla Block, Jordan Davis, Scotty Emerick, Brett Favre, Brantley Gilbert, HARDY, Tyler Hubbard, Krystal Keith, Ella Langley, Leanne Morgan, Mac McAnally and Clay Walker will all take the stage and sing some of Keith’s biggest hits. The show will be held tonight at Bridgestone Arena in Nashville, and will air on NBC as a two-hour special on August 28.
