Thousands came together for a mass sing-a-long in memory of the Manchester Arena attack victims in the city's Albert Square.
Around 3,000 choir singers performed at the Manchester Together concert, leading up to 15,000 amateur voices in an evening of solidarity through music.
The uplifting event saw people unite to sing four songs, including Ariana Grande's One Last Time, to remember the bombing on May 22 last year.
It also featured performances by parents and children who survived the blast that killed 22 and injured hundreds more.
Chimes rang out across the city at 10.31pm to mark the exact moment the attack was carried out one year ago.
The night opened with a series of video messages on the big screen from some famous names - including many Mancunians.
To loud cheers, Manchester United great Ryan Giggs said: "Manchester is a city of music and is a city of love, and we are sending out love and prayers on this emotional day."
Mani from The Stone Roses said: "One voice Manchester. Sing it up."
While Liam Fray, of The Courteeners, said: "We are a proud city of love and I will be thinking of each and every one of you on this very emotional and very difficult day."
In other video messages, musician Johnny Marr, formerly of The Smiths, said: "I wish I was with you tonight.
"My heart is always going to be in Manchester, always has been and always will be.
"I am proud to be a Mancunian.
"I am sure it will be an emotional occasion."
Shaun Ryder, of the Happy Mondays, said: "I am thinking of you. In fact I know I love you all big time massive.
"I am going to send 0161 love and peace vibes to the world."
Speaking on stage, the Lord Mayor of Manchester, Councillor Joan Hitchen, said: "Tonight the city of Manchester continues to demonstrate our solidarity to those who were affected by the terrible events of one year ago."
She thanked the brave men and women of the various emergency responders who helped "bring our Manchester together again".
The crowd responded with huge applause as she said: "Weren't they brilliant?"
She went on: "We also stand in solidarity with each other as Mancunians and tonight we are going to show the world that we stand together."
The Bishop of Manchester, the Rt Rev Dr David Walker, told the audience: "We are a city of music so it is appropriate that we come together to let our music come to the forefront of who we are.
"We are going to hear some fantastic choirs tonight. That is the the way we do things together.
"Doing things together makes us stronger and makes us Manchester."
Poet Tony Walsh returned to Albert Square where last May he read his poem This Is The Place at the public vigil to widespread acclaim.
After an earlier minute's silence, Mr Walsh encouraged the crowd to make a minute's noise for the 22, those injured in the blast, for the first responders, NHS staff involved in the care of those affected and "for Manchester and its spirit and its amazing people".
As the crowd of up to 15,000 people responded, Walsh shouted: "This is what love sounds like. You can't stop the sound of love."
Among those singing were Manchester Survivors Choir whose members were caught up in the blast at the Manchester Arena and joined together musically to help cope with the trauma of May 22.
Before they sang Rise Up by Andra Day, choir member Cath Hill told the audience: "We are showing Manchester and the world that we carry on.
"It is so important for us to be together. We are here to look after each other, care for each other and to be positive and move forward."
The uplifting evening was brought to a close by a 30-minute mass singalong comprising of the 2,800 voices of the various choirs and the many thousands who had gathered.
Noel Gallagher, Elbow's Guy Garvey and Gary Barlow gave short video messages ahead of their hits Don't Look Back In Anger, One Day Like This and Never Forget being sang.
Ariana Grande's One Last Time was also sang by the crowd before the event finished with a performance of The Beatles' All You Need Is Love.
