Could one of the biggest duos in alternative be getting back together? We will have to wait and see.

Former Oasis front man Liam Gallagher promised fans “some serious RnR” on Twitter today.  According to the Guardian, Gallagher is preparing for a Tuesday show at Manchester’s O2 Ritz with all the proceeds going to the families of victims of the bombing attack in the same English city just eight days ago.

The timing of tonight’s show has reignited rumors and speculation that Liam could reunite with his brother, Noel. Insiders close to Gallagher refused interview requests, stating that tonight’s charity show would be an  “incredible, emotional gig – and there are a few surprises too”. Oasis’s hit track ‘Don’t Look Back in Anger’ was sung by a crowd of mourners this past week who had gathered to remember the attack victims. An online video of the moving scene quickly started create even more demand for the Galagher reunion.

Liam and Noel Gallaghar of UK alt-giants Oasis have not played together in eight years, amid a bitter feud that has been well documented. So seeing the Gallaghers back together would be a huge moment, especially considering how it will benefit those affected by the awful Manchester attack.

The reunion rumors got very hot on Monday when Liam wished his brother Noel, a happy birthday.
