Okay I'm happy he still performed this song just cuz it's the only one direction song I really like but it's sad the others were not in it. Also I always get so concerned when I see him use that much energy on stage cuz he could have a attack again. I get he wants his fans to be satisfied with paying so much to see him but I don't think they want to pay to watch him struggle to breathe. In many of his live performances I notice he is having trouble breathing.
