It was a joyous, inspiring, emotional evening for the people of Manchester and no doubt the world, who watched the One Love Manchester benefit concert for the better part of three hours, streaming live on Facebook and Twitter.

Fifty thousand people packed the Old Trafford Cricket Grounds in remembrance of the 22 killed and more than 100 injured during the suicide bombing attack two weeks ago at pop singer Ariana Grande’s concert.

Many young girls, with their parents, sang and cried together. Others danced with British first responders – heroes over the course of these recent attacks.

Grande spearheaded the concert. The 23-year-old singer sang her hits, but also duets with others. In a particularly emotional moment, she embraced and sang with a young girl and a choir.

“I love you guys so much, and I think the kind of love and unity that you’re displaying is the kind of medicine the world really needs right now,” Grande said.

The concert also included Justin Bieber and Miley Cyrus, who sang with Ariana. Coldplay, Katy Perry, Pharrell Williams and the Black Eyed Peas also performed.

Organizers say shows of support like these are so important in the face of terror.

“Last night [Saturday], this nation was challenged and all of you were challenged and you had a decision to make if you were going to come out here tonight. And this is so beautiful. You guys made that decision, you looked that fear right in the face and said, ‘No. We are Manchester and the world is watching.’”

All proceeds for the concert will go directly to the victim’s families. That number is expected to be in the millions.
