Olly Murs' sold-out show in Glasgow was unexpectedly cut short on Thursday after just 20 minutes.
The 41-year-old former X Factor star managed to perform only six songs at the Hydro before informing the audience: “My voice has gone.”
“I've never experienced this before, but you can hear my voice is going,” Murs explained.
“I want to give you the concert you deserve, so I can’t go on. I’m going to come back, but I need to go now.”
The audience fell silent as the lights were raised, and fans, who had paid upwards of £57.55 for tickets, were asked to leave the Ovo Hydro venue.
A disappointed concertgoer told The Scottish Sun: “We were just getting into it after seeing Blue as the support act. He sang five songs, then suddenly stopped.

“He said he’d figure something out, but before we knew it, we were being told to leave.”
In a video posted to Instagram stories, the 41-year-old offered his audience an apology “from the bottom of my heart”, telling fans he was “so sorry”.
“I’ve never done this in 15 years,” he said. “Most of the time, as singers, you can get through it if your voice is not 100% and I walked out tonight thinking my voice is great.
“I felt a little bit rundown but I didn't think I couldn't do the show or I wouldn't have come out.
“As you can probably hear from my voice it just sounded rubbish and it is unfair for you guys who have spent all that money to come and see me, you deserve the best show and me at my best.”
Murs said he would see a doctor later that evening ahead of shows in Manchester, Birmingham and London over the weekend.
“It’s unfair for you guys who spent all that money to come and see me, you deserve the best show,” he said. “Hopefully, I can recover from this.”

This isn’t the first time Murs has had to cancel a show in Glasgow. Last May, he was forced to pull out of his opening performance for Take That just minutes before taking the stage.
Additionally, this year, Murs has faced multiple health issues, leading to the cancellation of other performances.
In February, he was scheduled to perform in Dubai but had to pull out just hours before taking the stage due to a throat infection.
The hitmaker took to Instagram to apologise, writing: “To everyone here in Dubai, unfortunately, due to doctor's orders, I have to cancel tonight's show at Bla-Bla because of a throat infection. I'm so gutted. I look forward to coming back ASAP and will share new date information soon! Olly x.”
He also shared a candid selfie, captioning it: “A man with a broken voice. Gutted Dubai, I’ll be back.”
