Oasis singer Liam Gallagher abruptly stormed off stage at a gig in London on Tuesday night (21July) after fans threw beer at him - leaving his brother NOEL to cover his vocals.
The rockers were performing at the Roundhouse venue in Camden, north London when a group of over-zealous audience members began hurling drinks at frontman Liam.
The star responded with a barrage of foul language, blaming "students" in "stupid pointy shoes" for the disturbance.
He then turned and left the stage, announcing, "I hope you feel as uncomfortable as I feel."
His brother Noel saw the funny side telling the audience at the venue in Camden, "I think someone's in a bad mood," and apologising for his sibling's temper tantrum.
Noel was then left to cover for his absent brother - singing lead vocals for almost half an hour.
Liam eventually returned to finished the set, and seemed unrepentant for the outburst, later writing on his Twitter.com page, "Camden, what a night."
The incident is the latest in a string of disagreements between the two siblings during the band's ongoing world tour.
The pair recently fell out when Liam asked the audience at a gig in Coventry, England to stop clapping their hands during the performance - with Noel criticising his brother for spoiling fans' fun.
