Rascal Flatts' first headlining show at Nashville's Gaylord Entertainment Center has been turned into a benefit for the Monroe Carell Jr. Children's Hospital at Vanderbilt. Tickets for the Sept. 24 show are $39, and the trio will be donating all proceeds to the hospital located on the campus of Vanderbilt University in Nashville. Blake Shelton and Keith Anderson will open the show. "We have been so blessed since we moved to town," says lead vocalist Gary LeVox. "The response from Nashville to this show has been so tremendous that we decided we wanted to give something back to the community." The group also recently filmed some public service announcements about the hospital that will air in the Nashville area.
