No, James Corden, don’t make Tituss Burgess sing! At an hour like this? With no preparation? He couldn’t possibly sing! Why, the only songs he knows are beloved Disney classics that perfectly fit his voice! And who’s going to sing backup — those two jokers sitting beside him who happen to have soothing baritones and a knack for harmony? Yeah, sure. The only way that will work is if Tituss Burgess is a preternaturally charming late-night guest.
