Oasis featured a green "Erin go Bragh" flag when they - finally - took the stage at Cardiff’s Principality Stadium for their long-awaited reunion on Friday, July 4.
Eagle-eyed fans took to social media to show off the green flag that was draped on one of the amps on stage.

The green 'Erin Go Bragh' flag is a precursor to Ireland's modern-day tricolor flag and is believed to have been used as early as 1642 by Owen Roe O’Neill, an Irish soldier and leader of the O’Neill dynasty.
Famously, it was flown by the San Patricios, the Irish-born and Irish-American soldiers who fought for Mexico during the Mexican-American War.
Today, the green 'Erin Go Bragh' flag is a symbol of Irish nationalism.

Elsewhere, in his article "Oasis are the greatest Irish band of all time" for The New Statesman, George Eaton observed: "Behind Noel on stage was a largely unnoticed green 'Éirinn go brách' ('Ireland forever') flag. This, far more than his rarely played Union Jack guitar (which was long ago confined to a museum), is a clue to the band’s real roots."

Indeed, the Irish roots of Oasis have never been in doubt.
Frontmen Noel and Liam Gallagher's parents are both from Ireland - their mother Margaret 'Peggy' is from Co Mayo, while their father Thomas 'Tommy' is from Co Meath.
"I was born and raised in Manchester but my mother is from Charlestown in County Mayo and my Dad’s from Duleek in Meath, so that makes me exactly half," Noel told host Gay Byrne on RTÉ's "The Late Late Show" in 1996.
"Although which half, I wouldn’t know," he joked.
Noel recounted holidays spent in Ireland during his youth: "My Mam used to religiously drag us by the ear over across the Irish Sea for six weeks [every summer].
"We’d never seen the likes of nettles and fields and stacks of hay and all that and she was determined to give us a bit of Irish culture because we were used to, like, concrete and flats and stuff.
"It was a bit of a culture shock for maybe the first four or five years, but we just grew to love it. I still do to this day.
"And the great thing, the other day was when we came up from the airport is, you know that smell is in the air when the like turf’s burning? It’s like as soon as you smell that it like almost brings a tear to your eye.
"It just reminds you of your childhood."

In 2008, Noel told the Irish Times how Irish music influenced Oasis songs: "The first music I was ever exposed to was the rebel songs the bands used to sing in the Irish club in Manchester.
"Do you know, I think that's where Oasis songs get their punch-the-air quality - from me being exposed to those rousing rebel songs.
"It was all rebel songs and that godawful Irish country and Western music."
More recently, Liam said last year that he'd be up for having none other than The Wolfe Tones open for Oasis when they perform in Dublin.
Should that come to pass, it would be a sort of full-circle moment for both of the iconic bands.
Wolfe Tones' frontman Brian Warfield previously said that he recalls the young Gallagher brothers attending the band's gigs in Manchester years ago.
“There were two kids who always showed up in Manchester to see us — Noel and Liam," Warfield told The Irish Sun in 2019.
“I remember them telling us, they were starting a band, it was only years later when I switched on the TV and saw them, I realized it was Oasis.”

But it's not just the Gallagher brothers who have Irish roots in Oasis, with Noel once remarking: “We were all from working-class Irish backgrounds."
Guitarist Paul 'Bonehead' Arthurs, whose mum is from Swinford in Co Mayo and dad is from Belfast, once said he had "typical Irish Catholic parents." Arthurs is back with the band for their reunion this year.
Meanwhile, former Oasis drummer Anthony 'Tony' McCarroll was honored with a plaque in his mother's hometown of Kinnitty, Co Offaly last year.
