On Sunday, Ariana bravely returned to Manchester to perform at One Love Manchester benefit concert with her star- studded friends. Fans encouraged Ariana to release the recording after she performed the Israel Kamakawiwoʻole classic at the end of the benefit concert.
Phil Andrews tweeted: @ArianaGrande please release somewhere over the rainbow as a charity single for Manchester so so fitting #OneLoveManchester'. "Somewhere Over the Rainbow".
The event saw stirring performances from a range of stars from Manchester's most notorious bad-boy Liam Gallagher to Coldplay, Katy Perry, Black Eyed Peas, Miley Cyrus and, as well a host of others, of course, Ariana Grande herself.
Ariana's decision to release the cover song comes after she also re-released her 2014 hit One Last Time, which she also performed live at the concert, as a charity single.
Cosmopolitan reported Monday that it was the first time the artist had incorporated the song into one of her stage shows.
Ever since the attack, Grande, 23, has been encouraging donations on social media and visited some still-recovering fans at Royal Manchester Children's Hospital on Friday.
Grande carried on with Sunday's show despite the attack in London the night before in which seven people were killed. Oasis was one of Manchester's most famous musical exports.

She said: "I had the pleasure of meeting Olivia's mummy a few days ago and I started to cry and gave her a big hug and she said 'stop crying, because Olivia wouldn't have wanted you to cry".
A source said: "This could be the most powerful song that will be heard all evening, because the lyrics are so relevant to how everyone now feels". We had a different show planned and we had a rehearsal yesterday and we changed everything'.
