Friday's (May 28) tribute to the late Gary Stewart has now also become a benefit for a college fund for the singer's grandson Joseph Stewart. Headliners at the concert are Wade Hayes, Radney Foster, Rosie Flores and Dean Dillon. The house band is the Texas Honky Tonky All Star Band, Stewart's longtime backing band. Showtime is 8 p.m. at The Trap in Nashville. Stewart died by suicide last December.
