Luke Bryan was a surprise last-minute addition to the all-network Hand in Hand hurricane relief concert on Tuesday night, but he’s not resting when he’s done. The singer has invited first responders to his Sept. 22 concert in Houston and turned it into a benefit for the Houston Community Fund.

Proceeds from next Friday’s show at the Cynthia Woods Mitchell Pavilion will go to the non-profit. The Huntin’, Fishin’ and Lovin’ Every Day Tour rushes through Texas next weekend, with stops in Austin, Houston and Dallas. After that he’ll begin the Farm Tour, which benefits a different charitable cause.

Early on during the Hand in Hand: A Benefit for Hurricane Relief concert Bryan was seen answering phones and taking donations. He's joined by dozens of celebrities including many from country music. Blake Shelton was the second performer, singing "Stand By Me" with Usher. Tim McGraw and Faith Hill are also slated to be there while George Strait, Miranda Lambert, Chris Stapleton and more will appear from San Antonio.

Viewers are encouraged to call 1-800-258-6000 to donate or text "Give" to 80077 to make a $25 donation. Several country stars like Chris Young and Granger Smith have gotten personally involved with the relief effort, setting up or supporting fundraising initiatives. Miranda Lambert brought her animal rescue charity to south Texas to help.
