Coldplay's Chris Martin, who led the audience in a massive "Don't Look Back in Anger" singalong and later joined Liam on stage for a rendition of "Live Forever" during the event, has since defended Noel.
We don't think our Oasis reunion dreams will EVER become a reality.
Now on holiday with his wife Sara MacDonald, Noel had been the subject of some criticism from fans, after Liam showed up to perform at the benefit gig without him, with Liam himself branding his older brother a "sad f***" on social media.
He is not the only artist donating song proceeds to the fund.
Ariana Grande makes triumphant return to Manchester
Coldplay has also taken their fair share of abuse from Liam Gallagher, who previously mocked the band's frontman Chris Martin for looking like a "geography teacher" and that "the whole band look beyond shit", according to NME.
Liam took to Twitter following his surprise appearance at the huge benefit gig, labeling his former Oasis bandmate and sibling a "sad fuck" and claimed he had "once again shown his true colours". Some reports suggested that Noel was not in Manchester because of a "longstanding family trip" that had been planned before the concert.
A crowd of people also performed a version of the same song which topped music charts after its release during a protest in St. Ann's Square, Manchester on the first Thursday after the attack.
During the show, Coldplay and Grande sang "Don't Look Back in Anger" together.
Musician Noel Gallagher did not play at the One Love charity concert in Manchester, but will donate profits from one of his songs to the fund (file pic). Loads of wonderful musicians from Manchester couldn't play the gig, but none of them have been dug out. That was before any gig was mentioned.
