Garth Brooks promised an informal acoustic performance with some friends but later surprised the crowd at Bass Performance Hall in Fort Worth, Texas, with a full-blown electric performance with his band. Brooks temporarily came out of retirement Sunday night (Feb. 13) to join singer-songwriters Steve Wariner, Stephanie Davis and Dan Roberts for a concert to raise money for Cook Children's Medical Center in Fort Worth. Following an intermission, Brooks returned to the stage for a solo acoustic performance of music that influenced him, a collection ranging from George Jones to Bob Seger. Then Brooks introduced his band and increased the volume with "Callin' Baton Rouge." During the set, Brooks performed several other hits, including "Rodeo," "Two of a Kind, Working on a Full House" and "The Thunder Rolls." With tickets priced at $1,000 each, the concert raised approximately $1.8 million for the medical center.
