Dierks Bentley, Walker Hayes and Shane McAnally will also perform at the Nashville show

By: Rolling Stone Thomas Rhett's wife, Lauren Akins spent time in Africa this summer on a mission trip with 147 Million Orphans, a non-profit organization that provides food, water, medicine and shelter to children living in poverty. She's now recruited her famous husband to help the cause out a little closer to home.

On October 4th, Rhett will share the stage with Dierks Bentley, Walker Hayes and Shane McAnally at Old School, a Nashville restaurant and event space. All proceeds will go to 147 Million Orphans, which works with impoverished children in Haiti, Honduras, Uganda and the United States — and raises awareness for the worldwide orphan crisis.

"Provision begins with the vulnerable child, but we also work to preserve families through sustainable income projects and community reconstruction," reads a statement on the foundation's website. "This support is critical to break the ongoing orphan crisis cycle."

Just after Rhett's infectious hit, "T Shirt" topped the charts, he designed his own T-shirt to benefit the charity.
