Bosses at the SSE Hydro have apologised to Westlife fans after seats weren't delivered in time for their concert in Glasgow - forcing them to stand throughout the whole gig.
The stage level seating area was changed to standing only for last night's gig at the last minute.
Some older fans weren't able to stay on their feet throughout the concert and had to leave early.
Ross Mitchell paid £200 for tickets to watch Westlife with his wife but decided to leave because he thought it would be too much to stand for several hours.
He said: "We could not face standing in a cramped atmosphere on the ground area of the arena.
"At 6.35pm I received an email to tell me that our hundred pounds each tickets five rows from the front were of no real value because the late arrival of the stars and their roadies meant they would have to build a hurried stage for tonight’s performance, the consequence of which was that all the floor seating would have to be removed and people already booked for the floor area would have to stand.
"I bought our tickets as a Christmas present for my wife - incidentally we are both in our seventies - and we so looked forward to the concert, but to stand for another three hours after standing in a queue outside for an hour, was a bit too much.
"We would have loved to see Westlife, but not under these circumstances. The only compensation is that we are assured the ticket suppliers will refund us."
Jack Williams had booked six tickets at a cost of £600 for his relatives who ended up leaving early.
He is angry that the change of seating plan wasn't communicated to gig-goers earlier in the day.
He said: "At 6.35pm I received an email saying that now all standing and if didn’t want to stand tough.
"By then my relatives, some in their 70s, had left to go to gig and of course the email was sent after box office closed
"Well found out two stood and left after an hour and 4 ended up here after paying top dollar."
In a statement on their website, the Hydro bosses apologised for the lack of seating.
The attributed the problem to 'transport delays'.
The statement read: "On behalf of the promoter of the event we apologise for any frustration or disappointment this may cause and appreciate your understanding."
