Ariana Grande has re-released "One Last Time," originally released as a single in 2015, as a benefit track on iTunes. All proceeds from the song's sales will go to the We Love Manchester Emergency Fund.

"All proceeds from each sale of the track featured on the page will be donated to the We Love Manchester Emergency Fund in coordination with the British Red Cross," Grande's Dangerous Woman tour update account shared on Twitter.

The singer performed "One Last Time" during her set at Manchester Arena on May 22, the location of the terror attack that took the lives of almost two dozen people and injured many more.

Grande is set to headline a benefit concert, One Love Manchester, Sunday (June 4), which iTunes will live stream in front of their paywall, with the show becoming available on demand right after it's over.

MTV also plans to live stream the concert, and Freeform will televise it. ABC will air a one-hour highlight special following its NBA Finals telecast. The concert will also be broadcast on more than 130 iHeartRadio stations.

Justin Bieber, Coldplay, Miley Cyrus, Katy Perry and Marcus Mumford are among the all-star lineup of performers taking part in the concert.
