It was already an emotional night at Ariana Grande’s Manchester benefit show, with empowering speeches and performances from several of her famous peers and the singer herself throughout. But it was one of her smallest, little-known guests who stole the show, and everyone’s hearts: Grande invited Manchester’s Parrs Wood High School choir to the stage to sing “My Everything,†re-creating their viral performance of the song at a tribute following the Manchester attack. This time, one of their youngest members got to duet with Grande in a moment that left not a dry eye in the house. Watch the touching performance above.
