The former Oasis rocker made an impromptu appearance at JJ Finan's pub in Charlestown on the west coast of Ireland over the weekend where he played a new song in which he seemed to be remorseful about his past.

During his performance - which footage of has since emerged online - he sang: "Yes I know, I've been wrong/ Didn't do what I was told/ Yes I know I've been wrong/ Didn't do what I was told/ I ain't looking for no 9-5/ Sick of wasting all my precious time/ Cos it's alright /Cos it's alright now."

One line also seemed to reference the most recent album from his estranged brother Noel Gallagher, 'Chasing Yesterday', with whom he has had a long-running feud.

He sang: "When I wake up and I hear you say/ There's no love worth chasing yesterday."

The 42-year-old performer hasn't released any music since his 2013 album with Beady Eye, 'BE', although a representative has denied he is working on a solo LP.

Meanwhile, Noel recently said he would consider reuniting Oasis following their split in 2009, but "only for the money".

He explained: "If I was ever going to do it, it would only be for the money. This isn't me putting it out there, by the way. Would I do it for charity? No way.

"But would we get back together one day? As long as everybody is still alive and still has their hair, it's always a possibility. But only for the money."
