Liam Gallagher has performed a new song in an Irish pub.

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.''
