OXFORD United fans are being urged to learn an Irish folk song written for the clubs’s FA Cup run and belt it out from the stands at Saturday’s clash with Blackburn Rovers.

The Corrigan Brothers, famous for their There’s No-one as Irish as Barack Obama hit, released a Cup song for the U’s and sent it to the club.

The trio were so inspired by United’s victory over Premier League Swansea City earlier this month they penned the song in time for the FA Cup fourth round.

The club has uploaded the song to their official YouTube account with a compilation of footage from Oxford’s third round giant-killing and clips of fans in the stands.

Lead singer Ger Corrigan hopes Over the Moon for Oxford United will be ringing out from the stands to inspire the U’s during Saturday’s game.

He said: “We want fans to download and share the song now ahead of Saturday’s game. Hopefully the tune will be sung out as Oxford keep their Cup run going.”

The band, which also features Brian and Donncha Corrigan, plan to play the track in the city centre before the FA Cup final in May if the team make it that far.

Oxford United spokesman Chris Williams said: “The Corrigan Brothers sent us the song after they recorded it. It’s great that the word about Oxford United has spread as far as Ireland.

“It’s just a bit of fun and hopefully they will have another song to write after Saturday’s game.”

The club said the tune was not an official club song but that it had released the audio and added the video.

The song is a rewrite of the Limerick trio’s most famous hit which they performed at Mr Obama’s official inauguration party at the president’s request.

It has previously been rejigged to feature Cardiff City’s controversial owner Vincent Tan, singer Susan Boyle and most recently Democratic Presidential candidate Martin O’Malley.

Part of the Yellow Army fan group, Joe Nicholls, 35, said: “It’s not particularly everyone’s cup of tea but for someone to change the song shows how impressive the win was against Swansea.”

The season-ticket holder said there was a real buzz across the county about the club’s recent form.

He said: “We have a strong fanbase anyway but over the past few weeks the excitement has been building across Oxfordshire.

“It’s been great hearing people talking about it in supermarkets and chip shops – and talking about going to watch the games.

“Saturday will be a tough game against a strong side but I think everyone, from the players to the fans, is confident we can win it.”
