A Liverpool song, sung in Manchester: proof that though football can turn neighbours into enemies, music brings everybody together.
The attack came at the end of a concert by US singer Ariana Grande who sent a message Tuesday to the people of Manchester.
Singer Ariana Grande is overcome by emotion at the One Love Manchester tribute concert on June 4, 2017. "I love you with all of me and am sending you all of the light and warmth I have to offer on this challenging day", she wrote along with a worker bee emoticon which is widely used to represent the city as a symbol of industry.
It concluded with a mass sing-along of five songs - Oasis' Don't Look Back In Anger, Elbow's One Day Like This, Grande's One Last Time, Take That's Never Forget and The Beatles' All You Need Is Love.
It seems the song continues to provide strength for the city, as the crowd sang during tonight's Albert Square gathering. The singer returned to Manchester two weeks later to perform at an all-star fundraising concert.
"This is Noel Gallagher, and I am here on behalf on Manchester Together In One Voice", said the former Oasis frontman via a video played to the crowd. "Love you so very much".
"I wish there was more that I could fix".

Ahead of the singing, the Bishop of Manchester, the Right Reverend David Walker, led those assembled in a minute's silence.
She added: 'We also stand in solidarity with each other as Mancunians and tonight we are going to show the world that we stand together.' Some 800 people had attended the hour-long service at Manchester Cathedral, including families and friends, along with front-line responders and volunteers who helped in the aftermath of the bombing.
Prince William the Duke of Cambridge and British Prime Minister Theresa May joined thousands of people who gathered in Manchester Tuesday on the first anniversary of a terror attack in the city which left 22 people dead.
On the altar stood 22 lit candles, made from the wax of thousands of candles left in the city's St. Ann's Square in the days after the attack.
'Part of the horror is that the arena appeared to have been deliberately chosen as a venue full of young people, ' he said.
At 10.31pm, bells rang out from the city's Town Hall, St Ann's Church and St Mary's RC Church to mark the moment when the attack took place 12 months ago.
Afterwards, Prince William met privately with some of the bereaved families and left a handwritten message on a Tree of Hope.
