The lead singer of 1980s band Echo And The Bunnymen has had assault charges found not proven but has been convicted of a breach of the peace.
McCulloch admitted a door hit Ms Sebley but said it was an accident
Ian McCulloch, 46, had been facing two charges of assault it was alleged took place backstage at Glasgow Barrowlands.
McCulloch told Glasgow District Court a female fan was accidentally struck by a door. But he was convicted of shouting and using threatening behaviour.
The Liverpool musician had been playing the venue in October last year.
He was convicted of committing a breach of the peace by shouting, swearing and threatening Gary Duncan, 39, and his girlfriend Juliet Sebley, 34.
The court heard that McCulloch lost his temper when he discovered the two fans in a toilet cubicle inside his private dressing room.
The pair tried to placate him by explaining they had been caught short and would be out in a moment, but McCulloch continued to shout at them.
In evidence, McCulloch claimed he had merely politely asked the couple to leave.
Stipendiary magistrate Robert Hamilton admonished McCulloch on the breach of the peace charge saying: "I'm going to take a very lenient view. This took place in an area where there were very few members of the public."
The incident took place at the Glasgow Barrowlands in 2005
The other charges McCulloch faced of assaulting Ms Sebley, from Glasgow, by kicking open a toilet door which struck her on the head, and assaulting Mr Duncan, also from Glasgow, by repeatedly pushing him were found not proven.
McCulloch admitted pushing the door open and hitting Ms Sebley but claimed it was an accident and denied assaulting Mr Duncan.
The singer said he found the couple together in a toilet cubicle situated inside his dressing room.
He said: "They were laughing and giggling. I felt uncomfortable. Two of the three cubicles were empty."
Mr Duncan, a mental health support worker from Glasgow, claimed that McCulloch launched a verbal tirade at him, challenged him to fight, dragged him by the lapels and repeatedly pushed him, on 23 October, last year.
He said that trouble flared when his girlfriend needed to go to the toilet and he went with her.
Ms Sebley told the court she suffered a cut and bruising to her head after the cubicle door was forced open.
She said: "I was very, very frightened."
They both denied a suggestion that they had been in the same toilet cubicle.
The couple said they had been invited backstage by a friend who knew one of the band's guitarists.
As he left court, McCulloch said that the conviction had not put him off playing gigs in Glasgow.
He said: "I love Glasgow. It is brilliant and the Barrowlands is the best venue in the world.
"I'm just glad it is all over. I look forward to playing Glasgow again."
