Noel Gallagher and Susan Sarandon are among nearly 50 high-profile figures who have signed an open letter backing the residents of Garvaghy Road.
They are joined by fellow music icons including Johnny Marr of The Smiths, Paul Weller of The Jam, and Madness frontman Suggs.
On Monday appeal court judges in Belfast reserved their judgment in a legal challenge regarding the Drumcree parading dispute.
Residents of the Garvaghy Road have been trapped in a dispute over a planned Orange Order march down the nationalist road on Sunday, 27 September.
Residents in the predominantly nationalist area, supported by Sinn Féin, the SDLP, and People Before Profit, previously failed in their court bid to overturn the decision, the Journal reported.
The Court of Appeal heard a new challenge on Monday, but the judges reserved their ruling, stating that no firm date for a verdict can be given yet.
Published on Tuesday, the open letter also features endorsements from high-profile figures, including Line of Duty star Adrian Dunbar, hip-hop trio Kneecap, singer Imelda May, Dexys Midnight Runners members Kevin Rowland and Sean Read, and Spider Stacy of The Pogues.
According to the Journal, in the letter they said the residents must be “robustly protected from any form of forced processions that disregard their consent, safety and right to live in peace free from intimidation”.
“The residents of the Garvaghy Road endured years of profound trauma, fear and disruption during the height of the parading conflicts in the 1990s," the letter continued.
It was stated that it is “entirely unacceptable” that the community should “face a return to that anxiety”.
“To allow old wounds to be aggressively reopened risks destabilising community relations not only in Portadown but across society in the North. We cannot afford to step backward. We urge you to exercise courageous political leadership at this critical juncture by looking to the international community for a neutral arbiter who can guide all sides toward a shared, peaceful future," it continued.
