Twenty-two people were killed and dozens were injured on May 22 when suicide bomber Salman Abedi detonated an explosive shortly after American star Ariana's show had ended. Miller previously canceled his scheduled performances over Memorial Day weekend at the Sasquatch Festival in Quincy, Washington, and Soundset in St. Paul, Minnesota, in wake of the bombing in Manchester following Grande's concert, which killed 22 people.
She then urged people to reach out and touch whoever was next to them and say "I love you" before performing Part Of Me and hit track Roar.
"From my friend Ariana Grande and the entire Dangerous Woman crew, myself and the rest of us around the world are so grateful to you for stepping up and taking action", he told the crowd at the Emirates Old Trafford cricket ground.
"I don't feel or smell or hear or see any fear in this building".
He also played his new solo single Wall Of Glass before he was joined on stage by Martin to play Oasis hit Live Forever, saying: "I want to dedicate this next song to the attractive people who were killed and injured in the Manchester terror attack".More news: Ariana Grande Benefit Concert Bieber Steals the Show ...

A third fan said that today's concert would be "really emotional".
Justin eventually did a prayer for the fallen victims of Manchester, and even asked the crowd to put both hands up in the air and to repeat after him in honoring those victims. "Just as I was about to leave the room, Adam looked at me and said, 'Hey, Scooter, make sure you tell them: 'Don't go forward in anger". But because of you, as a worldwide community, we will be fearless, will will be great and we will honor our children. Grande surprised young fans injured in the Manchester Arena attack, hugging the thrilled little girls in their hospital beds as they recovered from injuries sustained in the May 22 suicide bombing.
The recent incident raised questions about the whether the benefit would proceed, but the One Love Manchester concert is still happening following the London Bridge attack. "Our response to this violence must be to come closer together, to help each other, to love more, to sing louder and to live more kindly and generously than we did before".
All proceeds from the event will go toward the "We Love Manchester Emergency Fund", in partnership with the British Red Cross and Manchester City Council.
Supermodel Cara Delevingne also wrote a statement, reminding Londoners to "stay safe" and "not let this break us". But all had stated their commitment to the benefit concert in the week leading up to the show.
