Tickets for the event at the NIA, one of only three gigs in the UK, went on sale on Friday, with a small number of fans queuing up overnight in a bid to be at front of the queue.

It was expected to sell out within hours but today it was revealed tickets were still available.

NIA spokesman Tara Tomes said there were four categories of tickets available – £175, £125, £95 and £55 – but admitted only the £55 and £175 tickets have sold out.

"We have limited availability on the other two price bands," she said.

"We never second guess that any show is going to sell-out."
