Last night Gambino, a.k.a. Donald Glover was on The Late Show to promote the returning Atlanta. Host Stephen Colbert asked him about the charming clip, which Glover said he'd seen after "so many people" sent it to him. Colbert then surprised him by bringing Charity Joy and her dad out on stage.
Watch the sweet moment above (skip to around the 7m 30 mark). As Glover himself says, "Childish Gambino's for the children, man."
