A concert promoter has apologised to furious fans of Sir Tom Jones after a show costing up to £95 per ticket ended early due to a power cut.
The Welsh singer had got some way through his Saturday night set in a field beside Alnwick Castle, Northumberland, when a generator apparently failed for a second time.
That meant fans of The Voice star had to make their way away from the venue in darkness, they said.
Angry gig-goers took to social media to complain about how the event was organised and Sophie Hall from Bristol even set up an online petition demanding answers from promoters Loose Cannon.
Neil Winterbottom, director of the Middlesbrough firm, said: "Unfortunately, during Sir Tom Jones's performance at Alnwick Castle, there was an issue with the generator power supply which meant that the concert finished abruptly.
"I wish to make it clear that this situation is not associated with the artist or his management team or Alnwick Castle.
"Loose Cannon Events employed an established company to supply the power generators and who are well-versed in supplying power to large events of this scale and we are investigating the incident.
"We are sorry to disappoint concert-goers with the abrupt end to the concert and all enquiries should be directed to email@example.com"
Before that apology, fans who had paid £45 for tickets, with the VIP section costing £95, and who had been banned from bringing in food and drink, vented their anger on Facebook and Twitter, demanding their money back.
Phil Mawson from Seaham, County Durham, wrote: "The entire planning and management of the event was poor in the extreme."
Jane Richards Henry said: "I await my FULL refund!!
"Tonight was a complete joke from start to finish! A birthday present ruined!"
Linda Hood said: "The children at the local infant school would've made a better job of organising the event!
"Immensely disappointed, Sir Tom was fabulous for the short time he was on stage.
"I know it won't happen, but I'd rather they re-organised the event for another date rather than getting a refund ... if we get one!!!!!"
Jiffy Fowler wrote: "Full refund please we paid to see Tom Jones not The Shadows!!!"
And Jane Hedley wrote to Sir Tom, saying: "What a shame that someone didn't do their job properly. You were fabulous though - gutted for you."
