However, Coldplay’s Chris Martin joined Gallagher onstage to perform “Live Forever,” a particularly touching moment during the concert that closed out his short set.
Gallagher joined the A-list group of musicians set to perform on Sunday, including Ariana Grande, Miley Cyrus, Justin Bieber, Katy Perry, Pharrell Williams, Usher, Take That, Coldplay, Niall Horan, Robbie Williams and more.
While fans were delighted with Gallagher’s performance, the overall mood at the concert was especially somber after a terrorist attack in London — which left seven dead and 48 injured after three men drove into a crowd and attacked with knives — occurred less than 24 hours ahead of the concert. However, the performers kept the mood upbeat, even if a few did tear up at certain points.
All proceeds from the concert, taking place at the Emirates Old Trafford stadium in the city, are going to the Red Cross’s Manchester Emergency Fund to help victims and families impacted by the May 22 attack in Manchester that left 22 dead and 116 injured. Those who were at Grande’s original gig — which is where the Manchester bombing took place — were offered free tickets, and additional tickets sold out in just six minutes.
The show is expected to raise around US$2.6 million.
