OneRepublic made their summer debut on the Summer Concert Series stage with Good Morning America and they had a special guest.
Toni took the stage to sing "Hallelujah" while photos of her father Chris Cornell and Chester Bennington scrolled across the screen behind her.
Wearing a white Soundgarden shirt, the overwhelming emotion was evident not only in Toni's eyes, but the audience who were all in tears.
Chester is the godfather of Toni's brother, Christopher.
