The concert venue officially reopened on Saturday (9 September) night with a benefit gig to build a memorial in remembrance of the 22 people killed by the bombings back in May.
As he insisted the victims would “never ever be forgotten”, comedian Peter urged concert goers to “move forward with love and not hate”.
“That’s how we win,” he told the 14,000-strong crowd at the We Are Manchester show.
“There’s been a lot of joy in this room over the years, including the night of 22 May, right up until the terrorist attack.
“These last four months have been incredibly painful,” he continued.
“Horrendous is putting it mildly. But that’s why you’re here - because we can’t let terrorists win.
“And I know the memories of that night will stay with us for a very long time but we’ve got to remember the good times and let them outweigh the bad.”
“It’s become some sort of anthem for defiance,” Noel said. “And every time you sing, we win.”
Singer Ariana Grande previously arranged a benefit concert in aid of those affected by the attacks, after the bomb was detonated at her gig at Manchester Arena on 22 May.
She has since been made an honorary citizen of the city, having raised millions for the We Love Manchester Emergency Fund.
