Marcus Mumford of Mumford & Sons has joined the lineup for “One Love Manchester,” the benefit concert taking place June 4 at Emirates Old Trafford stadium outside of Manchester. Organized by Ariana Grande and her manager Scooter Braun, the show will also feature Justin Bieber, Coldplay, Katy Perry, Miley Cyrus, Pharrell Williams, Usher, Take That, and Niall Horan, among others.

The concert will be broadcast on BBC Television, and on BBC Radio and Capital Radio Networks in the U.K.; ABC and Freeform in the U.S. and on iHeartRadio stations, MTV Networks, YouTube and other digital networks throughout the world.

Some 50,000 are expected to attend with all net ticket proceeds going directly to the We Love Manchester Emergency Fund, which was set up by the Manchester City Council in partnership with the British Red Cross, in aid of grieving families and victims of the May 22 terrorist attack outside the Manchester Arena as an Ariana Grande concert was letting out. A suicide bomber took the lives of 22 people that night and injured dozens more.
