OK Carpool Karaoke fans, you know the drill. James Corden is awesome. His guests, who are always top-level, successful musicians, always partake in his segment with the utmost glee. The show has been so consistently excellent that you almost take it for granted.
Because it seems like with every session, there's always a special moment that just defines the entire episode. For Sam Smith's appearance with James Corden, it's when they unexpectedly picked up Fifth Harmony and the four-woman pop group packed into the backseat, which made Smith very, very happy.
