Coldplay have subtly come to the defense of Noel Gallagher after his brother and fellow former Oasis bandmate Liam slammed him on Twitter for not appearing Sunday’s One Love Manchester benefit concert.

At the show, Coldplay’s Chris Martin and guitarist Jonny Buckland covered Oasis’ classic “Don’t Look Back in Anger” — dedicating it to show organizer Ariana Grande — and performed with Liam on the group’s “Live Forever.”

In the wee hours of Monday, Liam took to Twitter to apologize for Noel’s absence, first gently and then, with a second Tweet, reigniting the brothers’ long feud. A spokesperson for Noel had said last week that he would not appear at the show because he was out of the country on a long-planned family trip. Still, fans hoped for an onstage reunion of the famously fractious siblings, who have not performed together in public since 2009. Twenty-plus years after they soared to superstardom, Manchester is still the brothers’ town, and their influence casts a huge shadow over the city’s musical history.

“Noels out of the f—ing country weren’t we all love get on a f—ing plane and play your tunes for the kids you sad f—.”

On Tuesday morning, Martin tipped the scales with a string of Tweets thanking Noel for his approval of their performance (punctuation added).

“Thank you @noelgallagher for giving your blessing and encouragement to play ‘Don’t Look Back in Anger’ and ‘Live Forever’ on Sunday.

Everyone knew in advance you couldn’t be there physically, so thank you for being there in spirit, and for lending us those incredible songs. Love cm”

And then, lest anyone think they were taking sides, Martin thanked Liam as well.

“And thank you @liamgallagher, that was awesome x cm + jb.”
