The View have postponed their London gig after Kyle Falconer punched his bandmate in an on-stage bust up on Wednesday night.
A sold out performance at The Deaf Institute in Manchester descended into chaos when lead singer Falconer was videoed swinging for bass guitarist Kieren Webster, who was celebrating his birthday.
The Dundee group have now postponed a gig at the Oslo Hackney in London tonight following the on-stage scrap which ended the show early.
Astounded fans videoed the incident and posted the footage on social media.
In the clip, Falconer can be seen appearing to punch Webster on the face before he is pulled back by guitarist Peter Reilly and other stage crew.
He can be heard saying I'll f****ng kill you."
In a separate video, Falconer performs an encore of Face for the Radio but tells the crowd Webster should come back on to finish the set.
As revellers jeer and shout his name, he replies: "The problem with this band is he wants to sing the songs and he canny, right, so I'll see you later."
It is understood he left with several songs still to be played from the set list, despite crew members trying to intervene and keep him on stage.
Disappointed fans who waited years for a comeback gig were then ordered to leave early, with many now calling for a refund.
A statement released on behalf of The View, from their management team, said: "Unfortunately, we are having to postpone tonight's London show.
"Our promoter is working to resolve the situation. Please keep hold of your tickets for now & we will make a further announcement in a few days. Massive apologies to all our fans."
