’AGT’ choir makes Simon Cowell cry with cover of late contestant Nightbirde’s ’It’s OK’

’AGT’ choir makes Simon Cowell cry with cover of late contestant Nightbirde’s ’It’s OK’: ’I know how much this would have meant to her’ Two years after singer-songwriter and cancer patient Nightbirde won America’s Got Talent judge Simon Cowell’s Golden Buzzer and heart — and millions of viewers’ hearts — with her optimistic original ballad “It’s OK,” her presence continued to be felt on this week’s AGT Season 18 premiere. At the emotional end of the episode, Soweto’s Mzansi Youth Choir put a triumphant spin on Nightbirde’s anthem — and they made Golden Buzzer history of their own.
