An email saying "We hope you enjoyed Ed Sheeran " has been sent to people who had tickets cancelled for the chart-topper's gig at Hampden Park last night.
Fans including emergency services workers - who booked tickets using the Blue Light Card service for NHS, social care sector, and armed forces - were only notified they could not attend the Glasgow concert just hours before it was due to start.
It is thought hundreds of ticket holders were affected by the late cancellation, with many of them left out of pocket after paying for travel and accommodation to attend the show.
