A SHOCKING video appearing to show Rangers fans singing an anti-Catholic song has been compared to an iconic scene from T2: Trainspotting.

In the footage, uploaded after Rangers lost 5-1 to Celtic on Saturday, fans can be heard chanting: “We hate Catholics, everybody hates Roman Catholics.”

At the start of the clip, filmed in what is believed to be an Orange Lodge filled with union jacks and Northern Irish flags, a horde of men can be seen wearing Rangers shirts and drinking.

With speakers blasting music in the background, the man a heard chanting a verse, which is difficult to hear.

They then get to the chorus, in which they sing: “Then you put your arms around and we stumble to the ground and we say we hate Catholics, everybody hates Roman Catholics.”

Several of the men can be seen pumping their fists to the tune, whilst one is clapping his hands to the beat.

Others are laughing and drinking their beers.

The video has been shared thousands of times since being posted on Twitter on Saturday, with many fans comparing it to a famous scene in T2: Trainspotting.

In the scene, Renton and Sick Boy are forced to sing anti-Catholic songs in a pub, after going in intending to steal credit cards.

Leading the shock reaction against the footage, Mogwai guitarist Stuart Braithwaite said: “I’ll be honest, I thought the orange lodge scene in Transpotting 2 was a bit over the top. How wrong I was Irvine Welsh.”

Padraig McAmb added: “The saddest thing about this is seeing young people there.”

David McK wrote: “Police Scotland take required action please. Plenty faces to publicise for identification.”

Sarah Coutts said: “That is disgusting!”

@Hotapethinks added: “Is Pedro not Catholic?” referring to new Rangers FC manager Pedro Caixinha.

A spokeswoman for Police Scotland said they could not comment on the video unless it was clear when and where it had been taken.
